"The Messenger of Allah (saas) often used to say: 'Allahumma thabbit qalbi 'ala dinika [O Allah, make my heart steadfast in (adhering to) Your religion].' A man said: 'O Messenger of Allah! Do you fear for us when we have believed in you and in (the Message) that you have brought?' He said: 'Hearts are between two of the fingers of the Most Merciful, and He controls them.'" (Hasan)Al-A'mash (one of the narrators) indicated with his fingers.

“The Messenger of Allah (saw) said: ‘Whoever abandons Friday (prayer) three times, for no necessary reason, Allah will place a seal over his heart.’”

“O Abu Hurairah, be cautious, and you will be the most devoted of people to Allah. Be content, and you will be the most grateful of people to Allah. Love for people what you love for yourself, and you will be a (true) believer. Be a good neighbor to your neighbors, and you will be a (true) Muslim. And laugh little, for laughing a lot deadens the heart.”

“How do you feel?” He said: “I have hope in Allah, O Messenger of Allah, but I fear my sins.” The Messenger of Allah (saw) said: “These two things (hope and fear) do not coexist in the heart of a person in a situation like this, but Allah will give him that which he hopes for and keep him safe from that which he fears.”

A man came to the Messenger of Allah (saws) and said: Teach me to read the Qur'an, Messenger of Allah.

He said: Read three surahs which begin with A.L.R. He said: My age is advanced, my mind has become dull (i.e. memory has grown weak), and my tongue has grown heavy). So he said: Then read three surahs which begin with H.M. He repeated the same words. So he said: Read three surahs which begin with the "Glorification of Allah". But he repeated the same excuse. The man then said: Teach me a comprehensive surah, Messenger of Allah. The Prophet (saws) taught him Surah (99). "When the Earth is shaken with her earthquake". When he finished it, the man said: By Him Who sent you with truth, I shall never add anything to it. Then man then went away.

The Prophet (saws) said twice: The man received salvation.

"The Messenger of Allah (SAW) said: 'Faith is knowledge in the heart, words on the tongue and action with the physical faculties. (limbs of the body).'" (Maudu')

"We used to come across groups of Quraish who would be talking, but they would stop talking (when we approached). We mentioned that to the Messenger of Allah and he said: 'What is the matter with people who talk, then when they see a man from my family they stop talking? By Allah, faith will not enter a person's heart until he loves them for the sake of Allah and because of their closeness to me.'"

Messenger of Allah(SAW) said: "There is no soul that died bearing witness to La ilaha illallah, and that I am the Messenger of Allah, from the heart with certainity, but Allah will forgive it."

“The Messenger of Allah (saw) went out one day to pray for rain. He led us in praying two Rak’ah without any Adhan or Iqamah, then he addressed us and supplicated to Allah. He turned to face the Qiblah, raising his hands, then he turned his cloak around, putting its right on the left and its left on the right.”

Yahya related to me from Malik from Nafi that Abdullah ibn Umar said, "Whoever swears by Allah and then says, 'Allah willing' and then does not do what he has sworn to, has not broken his oath."

Malik said, "The best I have heard on this reservation is that it belongs to the statement made if the speaker does not break the normal flow of speech before he is silent. If he is silent and breaks the flow of speech, he has no exception."

Yahya said, "Malik said that a man who said that he had disbelieved or associated something with Allah and then he broke his oath, had no kaffara, and he was not a disbeliever or one who associated something with Allah unless his heart concealed something of either of those. He should ask forgiveness of Allah and not return to it - for what he did was evil."

Sa'eed bin Abi Sa'eed Al-Maqburi narrated that Abu Salamah informed him that he had asked Aishah: "How was the Salat of Allah's Messenger (A) [at night] during Ramadan?" She said: "Allah's Messenger (S) would pray - neither in Ramadan nor in any other month - more than eleven Rak'ah. He would pray four, and do not ask about their excellence or length, then he would pray four, and do not ask about their excellence or length, then he would pray three." Aishah said: "I asked: 'O Messenger of Allah! Do you sleep before having performed Witr?" He said: 'O Aishah! Indeed my eyes sleep but my heart does not sleep.'"

"Allah's Messenger said: 'Whoever neglects the Friday prayer three times (in a row) without an excuse, then Allah sets a seal upon his heart.'"

The Prophet entered upon a young man while he was dying. So he said: "How do you feel?" He said: "By Allah! O Messenger of Allah! Indeed I hope in Allah and I fear from my sins." So the Messenger of Allah said: "These two will not be gathered in a worshipper's heart at a time such as this, except that Allah will grant him what he hopes and make him safe from what he fears."

From his father, from his grandfather, that the Prophet (saws) said: "Whoever asks Allah for Martyrdom sincerely in his heart, Allah will grant the status of martyrdom for him, even if he were to die in his bed."

[Abu 'Eisa said:] This Hadith is Hasan Gharib as a narration of Sahl bin Hunaif. We do not know of it except from the report of 'Abdur-Rahman bin Shuraih. 'Abdullah bin Salih reported it from 'Abdur-Rahman bin Shuraih, and 'Abdur-Rahman bin Shuraih's kunyah is Abu Shuriah, and he is from Iskandarani.

There is something on this topic from Mu'adh bin Jabal.

from Ibn 'Umar, that the Messenger of Allah (SAW) said: "Indeed Allah has put the truth upon the tongue and in the heart of 'Umar." He said: "And Ibn 'Umar said: 'No affair occurred among the people, except that they said something about it, and 'Umar said something about it'" or he said - "Ibn Al-Khattab" - Kharijah (one of the narrators) had a doubt about it - "except that the Qur'an was revealed in line with what 'Umar had said."

from 'Abdullah bin Unais Al-Juhni who said: "The Messenger of Allah (SAW) said: 'Indeed among the worst of the major sins is Shirk with Allah, disobeying the parents, the false oath, and none insists on taking an oath in which he swears, including the like of a wing of a mosquito (of falsehood) in it - except that a spot is placed in his heart until the Day of Judgement.'"

Are you visiting Hasan [during his sickness] when you feel what you feel? He said to him. Yes; you are not the Lord of my heart, to direct it as you wili. `Ali (رضي الله عنه) said: That does not prevent me from giving you advice, I heard the Messenger of Allah (ﷺ) say: “There is no Muslim who visits a [sick] Muslim, but Allah will send to him seventy thousand angels who will send blessings upon him from whatever hour of the day it is until evening comes, and from whatever hour of the night it is until morning comes.`

When the mu’adhdhin says, “God is most great, God is most great,” and one of you makes the response, “God is most great, God is most great”; then says, “I testify that there is no god but God,” and he makes the response, “I testify that there is no god but God”; then says, “I testify that Muhammad is God’s Messenger,” and he makes the response, “I testify that Muhammad is God’s Messenger”; then says, “Come to prayer,” and he makes the response, “There is no might and no power except in God”; then says, “Come to salvation,” and he makes the response, “There is no might and no power except in God”; then says, “God is most great, God is most great,” and he makes the response, “God is most great, God is most great”; then says, “There is no god but God,” and he makes the response, “There is no god but God”; if he says this from his heart, he will enter paradise. Muslim transmitted it.

I went to Ubayy b. Ka’b and said him : I am confused about Divine decree, so tell me something by means of which Allah may remove the confusion from my mind. He replied : were Allah to punish everyone in the heavens and in the earth. He would do so without being unjust to them, and were he to show mercy to them his mercy would be much better than their actions merited. Were you to spend in support of Allah’s cause an amount of gold equivalent to Uhud, Allah would not accept it from you till you believed in divine decree and knew that what has come to you could not miss you and that what has missed you could not come to you. Were you to die believing anything else you would enter Hell. He said : I then went to ‘Abd Allah b. MAs’ud and he said something to the same effect. I next went to Hudhaifah b. al-Yaman and he said something to the same effect. I next went to Zaid b. Thabit who told me something from the Prophet (May peace be upon him) to the same effect.

“I came to ‘Abdullah bin ‘Amr bin ‘As when he was sitting in the shade of the Ka’bah, and the people were gathered around him, and I heard him say: ‘While we were with the Messenger of Allah (saw) on a journey, he stopped to camp and some of us were pitching tents, some were competing in shooting arrows and some were taking the animals out to graze them. Then his caller called out: “As-Salatu Jami’ah (prayer is about to begin).” So we gathered, and the Messenger of Allah (saw) stood up and addressed us. He said: “There has never been a Prophet before me who was not obliged to tell his nation of what he knew was good for them, and to warn against what he knew was bad for them. With regard to this nation of yours, soundness (of religious commitment) and well-being has been placed in its earlier generations and the last of them will be afflicted with calamities and things that you dislike. Then there will come tribulations which will make the earlier ones pale into significance, and the believer will say: ‘This will be the end of me,’ then relief will come. Then (more) tribulations will come and the believer will say: ‘This will be the end of me,’ then relief will come. Whoever would like to be taken far away from Hell and admitted to Paradise, let him die believing in Allah and the Last Day, and let him treat people as he would like to be treated. Whoever gives his oath of allegiance to a ruler and gives a sincere promise, let him obey him as much as he can, and if another comes and challenges him, let them strike the neck (i.e., kill) the second one.’” He the narrator said: “I raised my head among the people and said: 'I adjure you by Allah, did you hear that from the Messenger of Allah (SAW)?' He ('Abdullah bin 'Amr bin Al-'As) pointed with his hand to his ears and said: I heard it directly from him and memorized it.'”

Ar-Rabi' ibn al-Hasan said, "I went with al-Hasan to visit Qatada. He sat by his head and asked after him and made supplication for him. He said, 'O Allah, heal his heart and cure him of his illness!"

I was near the House (i. e. Ka'bah) in a state between sleep and wakefulness when I heard someone say: He is the third among the two persons. Then he came to me and took me with him. Then a golden basin containing the water of Zamzam was brought to me and my heart was opened up to such and such (part). Qatada said: I asked him who was with me (i e. the narrator) and what he meant by such and such (part). He replied: (It means that it was opened) up to the lower part of his abdomen (Then the hadith continues): My heart was extracted and it was washed with the water of Zamzam and then it was restored in its original position, after which it was filled with faith and wisdom. I was then brought a white beast which is called al-Buraq, bigger than a donkey and smaller than a mule. Its stride was as long as the eye could reach. I was mounted on it, and then we went forth till we reached the lowest heaven. Gabriel asked for the (gate) to be opened, and it was said: Who is he? He replied: Gabriel. It was again said: Who is with thee? He replied: Muhammad (may peace be upon him). It was said: Has he been sent for? He (Gabriel) said: Yes. He (the Prophet) said: Then (the gate) was opened for us (and it was said): Welcome unto him! His is a blessed arrival. Then we came to Adam (peace be upon him). And he (the narrator) narrated the whole account of the hadith. (The Holy Prophet) observed that he met Jesus in the second heaven, Yahya (peace be on both of them) in the third heaven, Yusuf in the third, Idris in the fourth, Harun in the fifth (peace and blessings of Allah be upon them). Then we travelled on till we reached the sixth heaven and came to Moses (peace be upon him) and I greeted him and he said: Welcome unto righteous brother and righteous prophet. And when I passed (by him) he wept, and a voice was heard saying: What makes thee weep? He said: My Lord, he is a young man whom Thou hast sent after me (as a prophet) and his followers will enter Paradise in greater numbers than my followers. Then we travelled on till we reached the seventh heaven and I came to Ibrahim. He (the narrator) narrat- ed in this hadith that the Prophet of Allah (may peace be upon him) told that he saw four rivers which flowed from (the root of the lote-tree of the farthest limits): two manifest rivers and two hidden rivers. I said: ' Gabriel! ...

"O Messenger of Allah, I have come to offer myself to you (in marriage)." The Messenger of Allah looked her up and down then lowered his head. When the woman saw that he was not saying anything about her, she sat down. A man among his Companions stood up and said: "O Messenger of Allah, if you do not want to marry her, then marry me to her." He said: "Do you have anything?" He said: "No, by Allah, I do not have anything." He said: "Look, even if it is only an iron ring." He went, then he came back and said: "No, by Allah, O Messenger of Allah, not even an iron ring, but this is my Izar (lower garment)" - Sahl said: "He did not have a Rida' (upper garment)" - "she can have half of it." The Messenger of Allah said: "What could she do with your Izar? If you wear it, she will not have any of it, and if she wears it, you will not have any of it." The man sat down for a long time, then he got up, and the Messenger of Allah saw him leaving, so he ordered that he be called back. When he came, he said: "What do you know of the Qur'an?" He said: "I know Surah such-and-such, and Surah such-and-such," and listed them. He said: "Can you recite them by heart?" He said: "Yes." He said: "Then I marry you to her on the basis of what you know of the Qur'an."

I and my father set out in search of knowledge to a tribe of the Ansar before their death (i. e. before the Companions of the Holy Prophet left the world) and I was the first to meet Abu Yasar, a Companion of Allah's Messenger (may peace be upon him) and there was a young man with him who carried the record of letters with him and there was a mantle prepared by the tribe of Ma'afiri upon him. And his servant too had a Ma'afiri mantle over him. My father said to him: My uncle, I see the signs of anger or that of agony on your face. He said: Yes, such and such person, the son of so and so, of the tribe of Harami owed me a debt. I went to his family, extended salutations and said: Where is he? They said: He is not here. Then came out to me his son who was at the threshold of his youth. I said to him: Where is your father? He said: No sooner did he hear your sound than he hid himself behind my mother's bedstead. I said to him: Walk out to me, for I know where you are. He came out. I said to him: What prompted you to hide yourself from me? He said: By God, whatever I would say to you would not be a lie. By Allah, I fear that I should tell a lie to you and in case of making promise with you I should break it, as you are the Companion of Allah's Messenger (may peace be upon him). The fact is that I was hard up in regard to money. I said: Do you adjure by Allah? He said: I adjure by Allah. I said: Do you adjure by Allah? He said: I adjure by Allah. I said: Do you adjure by Allah? He said: I adjure by Allah. Then he brought his promissory note and he wrote off (the debt) with his hand and said: Make payment when you find yourself solvent enough to pay me back; if you are not, then there is no liability upon you. These two eyes of mine saw, and he (Abu'I-Yasar) placed his fingers upon his eyes and these two ears of mine heard and my heart retained, and he pointed towards his heart that Allah's Messenger (may peace be upon him) said: He who gives time to one who is financially hard up (in the payment of debt) or writes off his debt, Allah will provide him His shadow. I said to him: My uncle, if you get the cloak of your servant and you give him your two clothes, or take his two clothes of Ma'afir and give him your cloak, then there would be one dress for you and one for him. He wiped my head and said: O Allah, bless the son of my brother. O, son of my brother, these two very eyes of mine saw and these two ears of mine listened ...
