Yahya related to me from Malik from Said ibn Abi Said al-Maqburi from Abu Shurayh al-Kabi that the Messenger of Allah, may Allah bless him and grant him peace, said, "Whoever believes in Allah and the Last Day should speak good or be silent. Whoever believes in Allah and the Last Day should be generous to his neighbour. Whoever believes in Allah and the Last Day, should be generous to his guest. His welcome is for a day and a night, and his hospitality is for three days. Whatever is more than that is sadaqa. It is not halal for a guest to stay with a man until he becomes a burden."

Allah's Apostle ascended the pulpit and said, "Nothing worries me as to what will happen to you after me, except the temptation of worldly blessings which will be conferred on you." Then he mentioned the worldly pleasures. He started with the one (i.e. the blessings) and took up the other (i.e. the pleasures). A man got up saying, "O Allah's Apostle! Can the good bring about evil?" The Prophet remained silent and we thought that he was being inspired divinely, so all the people kept silent with awe. Then the Prophet wiped the sweat off his face and asked, "Where is the present questioner?" "Do you think wealth is good?" he repeated thrice, adding, "No doubt, good produces nothing but good. Indeed it is like what grows on the banks of a stream which either kills or nearly kills the grazing animals because of gluttony except the vegetation-eating animal which eats till both its flanks are full (i.e. till it gets satisfied) and then stands in the sun and defecates and urinates and again starts grazing. This worldly property is sweet vegetation. How excellent the wealth of the Muslim is, if it is collected through legal means and is spent in Allah's Cause and on orphans, poor people and travelers. But he who does not take it legally is like an eater who is never satisfied and his wealth will be a witness against him on the Day of Resurrection."

Today a man came to me and asked me a question which I did not know how to answer. He said, "Tell me, if a wealthy active man, well-equipped with arms, goes out on military expeditions with our chiefs, and orders us to do such things as we cannot do (should we obey him?)" I replied, "By Allah, I do not know what to reply you, except that we, were in the company of the Prophet and he used to order us to do a thing once only till we finished it. And no doubt, everyone among you will remain in a good state as long as he obeys Allah. If one is in doubt as to the legality of something, he should ask somebody who would satisfy him, but soon will come a time when you will not find such a man. By Him, except Whom none has the right to be worshipped. I see that the example of what has passed of this life (to what remains thereof) is like a pond whose fresh water has been used up and nothing remains but muddy water."

Yahya related to me from Malik from Zayd ibn Aslam from a man of the Bani'd-Dil called Busr ibn Mihjan from his father Mihjan that he was in a gathering with the Messenger of Allah, may Allah bless him and grant him peace, and the call to prayer was made. The Messenger of Allah, may Allah bless him and grant him peace, rose and prayed and then returned. Mihjan remained sitting and did not pray with him. The Messenger of Allah, may Allah bless him and grant him peace, said, "What prevented you from praying with the people? Aren't you a muslim?" He said, "Of course, Messenger of Allah, but I have already prayed with my family." The Messenger of Allah, may Allah bless him and grant him peace, said, "When you come, pray with the people, even if you have prayed already."

The Prophet ascended the mountain of Uhud and he was accompanied by Abu Bakr, `Umar and `Uthman. The mountain shook beneath them. The Prophet hit it with his foot and said, "O Uhud ! Be firm, for on you there is none but a Prophet, a Siddiq and a martyr (i.e. and two martyrs).

Malik bin Sasaa said that Allah's Apostle described to them his Night Journey saying, "While I was lying in Al-Hatim or Al-Hijr, suddenly someone came to me and cut my body open from here to here." I asked Al-Jarud who was by my side, "What does he mean?" He said, "It means from his throat to his pubic area," or said, "From the top of the chest." The Prophet further said, "He then took out my heart. Then a gold tray of Belief was brought to me and my heart was washed and was filled (with Belief) and then returned to its original place. Then a white animal which was smaller than a mule and bigger than a donkey was brought to me." (On this Al-Jarud asked, "Was it the Buraq, O Abu Hamza?" I (i.e. Anas) replied in the affirmative). The Prophet said, "The animal's step (was so wide that it) reached the farthest point within the reach of the animal's sight. I was carried on it, and Gabriel set out with me till we reached the nearest heaven. When he asked for the gate to be opened, it was asked, 'Who is it?' Gabriel answered, 'Gabriel.' It was asked, 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has Muhammad been called?' Gabriel replied in the affirmative. Then it was said, 'He is welcomed. What an excellent visit his is!' The gate was opened, and when I went over the first heaven, I saw Adam there. Gabriel said (to me). 'This is your father, Adam; pay him your greetings.' So I greeted him and he returned the greeting to me and said, 'You are welcomed, O pious son and pious Prophet.' Then Gabriel ascended with me till we reached the second heaven. Gabriel asked for the gate to be opened. It was asked, 'Who is it?' Gabriel answered, 'Gabriel.' It was asked, 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel answered in the affirmative. Then it was said, 'He is welcomed. What an excellent visit his is!' The gate was opened. When I went over the second heaven, there I saw Yahya (i.e. John) and `Isa (i.e. Jesus) who were cousins of each other. Gabriel said (to me), 'These are John and Jesus; pay them your greetings.' So I greeted them and both of them returned my greetings to me and said, 'You are welcomed, O pious brother and pious Prophet.' Then Gabriel ascended with me to the third heaven and asked for its gate to be opened. It was asked, 'Who is it?' Gabriel replied, 'Gabriel.' It was asked, 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel replied in the affirmative. Then it was said, 'He is welcomed, what an excellent visit his is!' The gate was opened, and when I went over the third heaven there I saw Joseph. Gabriel said (to me), 'This is Joseph; pay him your greetings.' So I greeted him and he returned the greeting to me and said, 'You are welcomed, O pious brother and pious Prophet.' Then Gabriel ascended with me to the fourth heaven and asked for its gate to be opened. It was asked, 'Who is it?' Gabriel replied, 'Gabriel' It was asked, 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel replied in the affirmative. Then it was said, 'He is welcomed, what an excel lent visit his is!' The gate was opened, and when I went over the fourth heaven, there I saw Idris. Gabriel said (to me), 'This is Idris; pay him your greetings.' So I greeted him and he returned the greeting to me and said, 'You are welcomed, O pious brother and pious Prophet.' Then Gabriel ascended with me to the fifth heaven and asked for its gate to be opened. It was asked, 'Who is it?' Gabriel replied, 'Gabriel.' It was asked. 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel replied in the affirmative. Then it was said He is welcomed, what an excellent visit his is! So when I went over the fifth heaven, there I saw Harun (i.e. Aaron), Gabriel said, (to me). This is Aaron; pay him your greetings.' I greeted him and he returned the greeting to me and said, 'You are welcomed, O pious brother and pious Prophet.' Then Gabriel ascended with me to the sixth heaven and asked for its gate to be opened. It was asked. 'Who is it?' Gabriel replied, 'Gabriel.' It was asked, 'Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel replied in the affirmative. It was said, 'He is welcomed. What an excellent visit his is!' When I went (over the sixth heaven), there I saw Moses. Gabriel said (to me),' This is Moses; pay him your greeting. So I greeted him and he returned the greetings to me and said, 'You are welcomed, O pious brother and pious Prophet.' When I left him (i.e. Moses) he wept. Someone asked him, 'What makes you weep?' Moses said, 'I weep because after me there has been sent (as Prophet) a young man whose followers will enter Paradise in greater numbers than my followers.' Then Gabriel ascended with me to the seventh heaven and asked for its gate to be opened. It was asked, 'Who is it?' Gabriel replied, 'Gabriel.' It was asked,' Who is accompanying you?' Gabriel replied, 'Muhammad.' It was asked, 'Has he been called?' Gabriel replied in the affirmative. Then it was said, 'He is welcomed. What an excellent visit his is!' So when I went (over the seventh heaven), there I saw Abraham. Gabriel said (to me), 'This is your father; pay your greetings to him.' So I greeted him and he returned the greetings to me and said, 'You are welcomed, O pious son and pious Prophet.' Then I was made to ascend to Sidrat-ul-Muntaha (i.e. the Lote Tree of the utmost boundary) Behold! Its fruits were like the jars of Hajr (i.e. a place near Medina) and its leaves were as big as the ears of elephants. Gabriel said, 'This is the Lote Tree of the utmost boundary) . Behold ! There ran four rivers, two were hidden and two were visible, I asked, 'What are these two kinds of rivers, O Gabriel?' He replied,' As for the hidden rivers, they are two rivers in Paradise and the visible rivers are the Nile and the Euphrates.' Then Al-Bait-ul-Ma'mur (i.e. the Sacred House) was shown to me and a container full of wine and another full of milk and a third full of honey were brought to me. I took the milk. Gabriel remarked, 'This is the Islamic religion which you and your followers are following.' Then the prayers were enjoined on me: They were fifty prayers a day. When I returned, I passed by Moses who asked (me), 'What have you been ordered to do?' I replied, 'I have been ordered to offer fifty prayers a day.' Moses said, 'Your followers cannot bear fifty prayers a day, and by Allah, I have tested people before you, and I have tried my level best with Bani Israel (in vain). Go back to your Lord and ask for reduction to lessen your followers' burden.' So I went back, and Allah reduced ten prayers for me. Then again I came to Moses, but he repeated the same as he had said before. Then again I went back to Allah and He reduced ten more prayers. When I came back to Moses he said the same, I went back to Allah and He ordered me to observe ten prayers a day. When I came back to Moses, he repeated the same advice, so I went back to Allah and was ordered to observe five prayers a day. When I came back to Moses, he said, 'What have you been ordered?' I replied, 'I have been ordered to observe five prayers a day.' He said, 'Your followers cannot bear five prayers a day, and no doubt, I have got an experience of the people before you, and I have tried my level best with Bani Israel, so go back to your Lord and ask for reduction to lessen your follower's burden.' I said, 'I have requested so much of my Lord that I feel ashamed, but I am satisfied now and surrender to Allah's Order.' When I left, I heard a voice saying, 'I have passed My Order and have lessened the burden of My Worshipers."

Allah's Apostle wrote to Caesar and invited him to Islam and sent him his letter with Dihya Al-Kalbi whom Allah's Apostle ordered to hand it over to the Governor of Busra who would forward it to Caesar. Caesar as a sign of gratitude to Allah, had walked from Hims to Ilya (i.e. Jerusalem) when Allah had granted Him victory over the Persian forces. So, when the letter of Allah's Apostle reached Caesar, he said after reading it, 'Seek for me any one of his people! (Arabs of Quraish tribe) if present here, in order to ask him about Allah's Apostle. At that time Abu Sufyan bin Harb was in Sham with some men from Quraish who had come (to Sham) as merchants during the truce that had been concluded between Allah's Apostle; and the infidels of Quraish. Abu Sufyan said, Caesar's messenger found us somewhere in Sham so he took me and my companions to Ilya and we were admitted into Ceasar's court to find him sitting in his royal court wearing a crown and surrounded by the senior dignitaries of the Byzantine. He said to his translator. 'Ask them who amongst them is a close relation to the man who claims to be a prophet." Abu Sufyan added, "I replied, 'I am the nearest relative to him.' He asked, 'What degree of relationship do you have with him?' I replied, 'He is my cousin,' and there was none of Bani Abu Manaf in the caravan except myself. Caesar said, 'Let him come nearer.' He then ordered that my companions stand behind me near my shoulder and said to his translator, 'Tell his companions that I am going to ask this man about the man who claims to be a prophet. If he tells a lie, they should contradict him immediately." Abu Sufyan added, "By Allah! Had it not been shameful that my companions label me a liar, I would not have spoken the truth about him when he asked me. But I considered it shameful to be called a liar by my companions. So I told the truth. He then said to his translator, 'Ask him what kind of family does he belong to.' I replied, 'He belongs to a noble family amongst us.' He said, 'Have anybody else amongst you ever claimed the same before him? 'I replied, 'No.' He said, 'Had you ever blamed him for telling lies before he claimed what he claimed? ' I replied, 'No.' He said, 'Was anybody amongst his ancestors a king?' I replied, 'No.' He said, "Do the noble or the poor follow him?' I replied, 'It is the poor who follow him.' He said, 'Are they increasing or decreasing (day by day)?' I replied,' They are increasing.' He said, 'Does anybody amongst those who embrace his (the Prophet's) Religion become displeased and then discard his Religion?'. I replied, 'No. ' He said, 'Does he break his promises? I replied, 'No, but we are now at truce with him and we are afraid that he may betray us." Abu Sufyan added, "Other than the last sentence, I could not say anything against him. Caesar then asked, 'Have you ever had a war with him?' I replied, 'Yes.' He said, 'What was the outcome of your battles with him?' I replied, 'The result was unstable; sometimes he was victorious and sometimes we.' He said, 'What does he order you to do?' I said, 'He tells us to worship Allah alone, and not to worship others along with Him, and to leave all that our fore-fathers used to worship. He orders us to pray, give in charity, be chaste, keep promises and return what is entrusted to us.' When I had said that, Caesar said to his translator, 'Say to him: I ask you about his lineage and your reply was that he belonged to a noble family. In fact, all the apostles came from the noblest lineage of their nations. Then I questioned you whether anybody else amongst you had claimed such a thing, and your reply was in the negative. If the answer had been in the affirmative, I would have thought that this man was following a claim that had been said before him. When I asked you whether he was ever blamed for telling lies, your reply was in the negative, so I took it for granted that a person who did not tell a lie about (others) the people could never tell a lie about Allah. Then I asked you whether any of his ancestors was a king. Your reply was in the negative, and if it had been in the affirmative, I would have thought that this man wanted to take back his ancestral kingdom. When I asked you whether the rich or the poor people followed him, you replied that it was the poor who followed him. In fact, such are the followers of the apostles. Then I asked you whether his followers were increasing or decreasing. You replied that they were increasing. In fact, this is the result of true faith till it is complete (in all respects). I asked you whether there was anybody who, after embracing his religion, became displeased and discarded his religion; your reply was in the negative. In fact, this is the sign of true faith, for when its cheerfulness enters and mixes in the hearts completely, nobody will be displeased with it. I asked you whether he had ever broken his promise. You replied in the negative. And such are the apostles; they never break their promises. When I asked you whether you fought with him and he fought with you, you replied that he did, and that sometimes he was victorious and sometimes you. Indeed, such are the apostles; they are put to trials and the final victory is always theirs. Then I asked you what he ordered you. You replied that he ordered you to worship Allah alone and not to worship others along with Him, to leave all that your fore-fathers used to worship, to offer prayers, to speak the truth, to be chaste, to keep promises, and to return what is entrusted to you. These are really the qualities of a prophet who, I knew (from the previous Scriptures) would appear, but I did not know that he would be from amongst you. If what you say should be true, he will very soon occupy the earth under my feet, and if I knew that I would reach him definitely, I would go immediately to meet Him; and were I with him, then I would certainly wash his feet.' " Abu Sufyan added, "Caesar then asked for the letter of Allah's Apostle and it was read. Its contents were: "In the name of Allah, the most Beneficent, the most Merciful (This letter is) from Muhammad, the slave of Allah, and His Apostle, to Heraculius, the Ruler of the Byzantine. Peace be upon the followers of guidance. Now then, I invite you to Islam (i.e. surrender to Allah), embrace Islam and you will be safe; embrace Islam and Allah will bestow on you a double reward. But if you reject this invitation of Islam, you shall be responsible for misguiding the tillers (i.e. your nation). O people of the Scriptures! Come to a word common to you and us and you, that we worship. None but Allah, and that we associate nothing in worship with Him; and that none of us shall take others as Lords besides Allah. Then if they turn away, say: Bear witness that we are (they who have surrendered (unto Him)..(3.64) Abu Sufyan added, "When Heraclius had finished his speech, there was a great hue and cry caused by the Byzantine Royalties surrounding him, and there was so much noise that I did not understand what they said. So, we were turned out of the court. When I went out with my companions and we were alone, I said to them, 'Verily, Ibn Abi Kabsha's (i.e. the Prophet's) affair has gained power. This is the King of Bani Al-Asfar fearing him." Abu Sufyan added, "By Allah, I remained low and was sure that his religion would be victorious till Allah converted me to Islam, though I disliked it."

Some people from the Ansar asked Allah's Apostle (to give them something) and he gave to everyone of them, who asked him, until all that he had was finished. When everything was finished and he had spent all that was in his hand, he said to them, '"(Know) that if I have any wealth, I will not withhold it from you (to keep for somebody else); And (know) that he who refrains from begging others (or doing prohibited deeds), Allah will make him contented and not in need of others; and he who remains patient, Allah will bestow patience upon him, and he who is satisfied with what he has, Allah will make him self-sufficient. And there is no gift better and vast (you may be given) than patience."

Yahya related to me from Malik from Hisham ibn Urwa that his father used to say to his sons, "My sons, let none of you sacrifice any animal which he would be ashamed to sacrifice for a noble woman, for surely Allah is the noblest of noble ones, and the most deserving of those for whom things are chosen."

We used to say that the warriors of Badr were over three-hundred-and-ten, as many as the Companions of Saul who crossed the river with him; and none crossed the river with him but a believer.

Abu Dawud said: This tradition has been narrated by Ibn al-Mubarak from Fulaih who heard ‘Abbas . Sahl narrating it; but I do not remember it. I think he made the mention of ‘Isa b. ‘Abd Allah who heard ‘Abbas b. Sahl saying: I accompanied Abu Humaid al-Sa’idi.

Sahl bin Abi Hathma and some great men of his tribe said, `Abdullah bin 'Sahl and Muhaiyisa went out to Khaibar as they were struck with poverty and difficult living conditions. Then Muhaiyisa was informed that `Abdullah had been killed and thrown in a pit or a spring. Muhaiyisa went to the Jews and said, "By Allah, you have killed my companion." The Jews said, "By Allah, we have not killed him." Muhaiyisa then came back to his people and told them the story. He, his elder brother Huwaiyisa and `Abdur-Rahman bin Sahl came (to the Prophet) and he who had been at Khaibar, proceeded to speak, but the Prophet said to Muhaiyisa, "The eldest! The eldest!" meaning, "Let the eldest of you speak." So Huwaiyisa spoke first and then Muhaiyisa. Allah's Apostle said, "The Jews should either pay the blood money of your (deceased) companion or be ready for war." After that Allah's Apostle wrote a letter to the Jews in that respect, and they wrote that they had not killed him. Then Allah's Apostle said to Huwaiyisa, Muhaiyisa and `Abdur-Rahman, "Can you take an oath by which you will be entitled to take the blood money?" They said, "No." He said (to them), "Shall we ask the Jews to take an oath before you?" They replied, "But the Jews are not Muslims." So Allah's Apostle gave them one-hundred she-camels as blood money from himself. Sahl added: When those she-camels were made to enter the house, one of them kicked me with its leg.

Yahya related to me from Malik that he had heard that Muhammad Sirin used to say, "Do not sell grain on the ears until it is white."

Malik said, "If someone buys food for a known price to be delivered at a stated date, and when the date comes, the one who owes the food says, 'I do not have any food, sell me the food which I owe you with delayed terms.' The owner of the food says, 'This is not good, because the Messenger of Allah, may Allah bless him and grant him peace, forbade selling food until the deal was completed.' The one who owes the food says to his creditor, 'Sell me any kind of food on delayed terms until I discharge the debt to you.' This is not good because he gives him food and then he returns it to him. The gold which he gave him becomes the price of that which is his right against him and the food which he gave him becomes what clears what is between them. If they do that, it becomes the sale of food before the deal is complete."

Malik spoke about a man who was owed food which he had purchased from a man and this man was owed the like of that food by another man. The one who owed the food said to his creditor, "I will refer you to my debtor who owes me the same amount of food as I owe you, so that you may obtain the food which I owe you ."

Malik said, "If the man who had to deliver the food, had gone out, and bought the food to pay off his creditor, that is not good. That is selling food before taking possession of it. If the food is an advance which falls due at that particular time, there is no harm in paying off his creditor with it because that is nota sale. It is not halal to sell food before receiving it in full since the Messenger of Allah, may Allah bless him and grant him peace, forbade that. However, the people of knowledge agree that there is no harm in partnership, transfer of responsibility and revocation in sales of food and other goods."

Malik said, "That is because the people of knowledge consider it as a favour rendered. They do not consider it as a sale. It is like a man lending light dirhams. He is then paid back in dirhams of full weight, and so gets back more than he lent. That is halal for him and permitted. Had a man bought defective dirhams from him as being the full weight, that would not be halal. Had it been stipulated to him that he lend full weight in dirhams, and then he gave faulty ones, that would not be halal for him."

When I entered upon Mu'awiyah, he said: How good your visit is to us, O father of so-and-so. (This is an idiom used by the Arabs on such occasions). I said: I tell you a tradition which I heard (from the Prophet). I heard the Messenger of Allah (saws) say: If Allah puts anyone in the position of authority over the affairs of the Muslims, and he secludes himself (from them), not fulfilling their needs, wants, and poverty, Allah will keep Himself away from him, not fulfilling his need, want and poverty. He said: He (Mu'awiyah) appointed a man to fulfil the needs of the people.

Yahya related to me from Malik from Yahya ibn Said that Zurayq ibn Hayyan, who was in charge of Egypt in the time of al-Walid, Sulayman, and Umar ibn Abd al-'Aziz, mentioned that Umar ibn Abd al- Aziz had written to him saying, "Assess the muslims that you come across and take from what is apparent of their wealth and whatever merchandise is in their charge, one dinar for every forty dinars, and the same proportion from what is less than that down to twenty dinars, and if the amount falls short of that by one third of a dinar then leave it and do not take anything from it. As for the people of the Book that you come across, take from the merchandise in their charge one dinar for every twenty dinars, and the same proportion from what is less than that down to ten dinars, and if the amount falls short by one third of a dinar leave it and do not take anything from it. Give them a receipt for what you have taken f rom them until the same time next year."

Malik said, "The position among us (in Madina) concerning goods which are being managed for trading purposes is that if a man pays zakat on his wealth, and then buys goods with it, whether cloth, slaves or something similar, and then sells them before a year has elapsed over them, he does not pay zakat on that wealth until a year elapses over it from the day he paid zakat on it. He does not have to pay zakat on any of the goods if he does not sell them for some years, and even if he keeps them for a very long time he still only has to pay zakat on them once when he sells them."

Malik said, "The position among us concerning a man who uses gold or silver to buy wheat, dates, or whatever, for trading purposes and keeps it until a year has elapsed over it and then sells it, is that he only has to pay zakat on it if and when he sells it, if the price reaches a zakatable amount. This is therefore not the same as the harvest crops that a man reaps from his land, or the dates that he harvests from his palms."

Malik said, "A man who has wealth which he invests in trade, but which does not realise a zakatable profit for him, fixes a month in the year when he takes stock of what goods he has for trading, and counts the gold and silver that he has in ready money, and if all of it comes to a zakatable amount he pays zakat on it."

Malik said, "The position is the same for muslims who trade and muslims who do not. They only have to pay zakat once in any one year, whether they trade in that year or not."

Yahya related to me from Malik from Suhayl ibn Abi Salih from his father from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, gave hospitality to a kafir guest. The Messenger of Allah, may Allah bless him and grant him peace, ordered a sheep to be brought for him and it was milked. He drank its milk. Then another came, and he drank it. Then another came and he drank it until he had drunk the milk of seven sheep. In the morning he became muslim, and the Messenger of Allah, may Allah bless him and grant him peace, ordered a sheep for him. It was milked and he drank its milk. Then he ordered another for him and he could not finish it. The Messenger of Allah, may Allah bless him and grant him peace, said, "The mumin drinks in one intestine, and the kafir drinks in seven intestines."

The Prophet (saws) said: If anyone intercedes for his brother and he presents a gift to him for it and he accepts it, he approaches a great door of the doors of usury.

AbuZumayl said: I asked Ibn Abbas, saying: What is that I find in my breast? He asked: What is it? I replied: I swear by Allah, I cannot speak about it. He asked me: Is it something doubtful? and he laughed. He then said: No one could escape that, until Allah, the exalted, revealed: "If thou went in doubt as to what we have revealed unto thee, and ask those who have been reading the Book from before thee." He said: If you find something in your heart, say: He is the first and the Last, the Evident and the Immanent, and He has full knowledge of all things.
