Umar (may Allah be pleased with him) took a vow in the pre-Islamic days to spend a night or a day in devotion near the Ka'bah (in the sacred mosque). He asked the Prophet (saws) about it. He said: Observe i'tikaf (i.e. spend a night or a day near the Ka'bah) and fast.

Yahya related to me from Malik from Muhammad ibn Yahya ibn Habban from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, forbade fasting on two days - the day of the Id al-Fitr and the day of the Id al-Adha.

I was with Ibn `Umar when a man asked him, "I have vowed to fast every Tuesday or Wednesday throughout my life and if the day of my fasting coincided with the day of Nahr (the first day of `Id-al- Adha), (What shall I do?)" Ibn `Umar said, "Allah has ordered the vows to be fulfilled, and we are forbidden to fast on the day of Nahr." The man repeated his question and Ibn `Umar repeated his former answer, adding nothing more.

Yahya related to me from Malik that he had heard the people of knowledge telling people not to fast on the day in Shaban when there was doubt (about whether it was Shaban or Ramadan), if they intended by it the fast of Ramadan . They considered that whoever fasted on that day without having seen (the new moon) had to make up that day if it later became clear that it was part of Ramadan. They did not see any harm in voluntary fasting on that day.

Malik said, "This is what we do, and what I have seen the people of knowledge in our city doing."

When Allah's Apostle arrived at Medina, he found the Jews observing the fast on the day of 'Ashura' (10th of Muharram). The Prophet asked them (about it) and they replied, "This is the day when Moses became victorious over Pharaoh." The Prophet said (to the Muslims), "We are nearer to Moses than they, so fast on this day."

The Prophet (saws) said: We forbade you to eat their meat for more than three days in order that you might have abundance; now Allah has produced abundance, so you may eat, store up and seek reward. Beware, these days are days of eating, drinking and remembrance of Allah, Most High.

'Ashura' (i.e. the tenth of Muharram) was a day on which the tribe of Quraish used to fast in the prelslamic period of ignorance. The Prophet also used to fast on this day. So when he migrated to Medina, he fasted on it and ordered (the Muslims) to fast on it. When the fasting of Ramadan was enjoined, it became optional for the people to fast or not to fast on the day of Ashura.

Some people said, "O Allah's Apostle! Shall we see our Lord on the Day of Resurrection?" He said, "Do you crowd and squeeze each other on looking at the sun when it is not hidden by clouds?" They replied, "No, Allah's Apostle." He said, "Do you crowd and squeeze each other on looking at the moon when it is full and not hidden by clouds?" They replied, No, O Allah's Apostle!" He said, "So you will see Him (your Lord) on the Day of Resurrection similarly Allah will gather all the people and say, 'Whoever used to worship anything should follow that thing. 'So, he who used to worship the sun, will follow it, and he who used to worship the moon will follow it, and he who used to worship false deities will follow them; and then only this nation (i.e., Muslims) will remain, including their hypocrites. Allah will come to them in a shape other than they know and will say, 'I am your Lord.' They will say, 'We seek refuge with Allah from you. This is our place; (we will not follow you) till our Lord comes to us, and when our Lord comes to us, we will recognize Him. Then Allah will come to then in a shape they know and will say, "I am your Lord.' They will say, '(No doubt) You are our Lord,' and they will follow Him. Then a bridge will be laid over the (Hell) Fire." Allah's Apostle added, "I will be the first to cross it. And the invocation of the Apostles on that Day, will be 'Allahumma Sallim, Sallim (O Allah, save us, save us!),' and over that bridge there will be hooks Similar to the thorns of As Sa'dan (a thorny tree). Didn't you see the thorns of As-Sa'dan?" The companions said, "Yes, O Allah's Apostle." He added, "So the hooks over that bridge will be like the thorns of As-Sa-dan except that their greatness in size is only known to Allah. These hooks will snatch the people according to their deeds. Some people will be ruined because of their evil deeds, and some will be cut into pieces and fall down in Hell, but will be saved afterwards, when Allah has finished the judgments among His slaves, and intends to take out of the Fire whoever He wishes to take out from among those who used to testify that none had the right to be worshipped but Allah. We will order the angels to take them out and the angels will know them by the mark of the traces of prostration (on their foreheads) for Allah banned the f ire to consume the traces of prostration on the body of Adam's son. So they will take them out, and by then they would have burnt (as coal), and then water, called Ma'ul Hayat (water of life) will be poured on them, and they will spring out like a seed springs out on the bank of a rainwater stream, and there will remain one man who will be facing the (Hell) Fire and will say, 'O Lord! It's (Hell's) vapor has Poisoned and smoked me and its flame has burnt me; please turn my face away from the Fire.' He will keep on invoking Allah till Allah says, 'Perhaps, if I give you what you want), you will ask for another thing?' The man will say, 'No, by Your Power, I will not ask You for anything else.' Then Allah will turn his face away from the Fire. The man will say after that, 'O Lord, bring me near the gate of Paradise.' Allah will say (to him), 'Didn't you promise not to ask for anything else? Woe to you, O son of Adam ! How treacherous you are!' The man will keep on invoking Allah till Allah will say, 'But if I give you that, you may ask me for something else.' The man will say, 'No, by Your Power. I will not ask for anything else.' He will give Allah his covenant and promise not to ask for anything else after that. So Allah will bring him near to the gate of Paradise, and when he sees what is in it, he will remain silent as long as Allah will, and then he will say, 'O Lord! Let me enter Paradise.' Allah will say, 'Didn't you promise that you would not ask Me for anything other than that? Woe to you, O son of Adam ! How treacherous you are!' On that, the man will say, 'O Lord! Do not make me the most wretched of Your creation,' and will keep on invoking Allah till Allah will smile and when Allah will smile because of him, then He will allow him to enter Paradise, and when he will enter Paradise, he will be addressed, 'Wish from so-and-so.' He will wish till all his wishes will be fulfilled, then Allah will say, All this (i.e. what you have wished for) and as much again therewith are for you.' " Abu Huraira added: That man will be the last of the people of Paradise to enter (Paradise).

Some people drank alcoholic beverages in the morning (of the day) of the Uhud battle and on the same day they were killed as martyrs, and that was before wine was prohibited.

The Prophet said (to `Abdullah), "Fast three days a month." `Abdullah said, (to the Prophet) "I am able to fast more than that." They kept on arguing on this matter till the Prophet said, "Fast on alternate days, and recite the whole Qur'an once a month." `Abdullah said, "I can recite more (in a month)," and the argument went on till the Prophet said, "Recite the Qur'an once each three days." (i.e. you must not recite the whole Qur'an in less than three days).

The Prophet did not do that (i.e., forbade the storage of the meat of sacrifices for three days) except (he did so) so that the rich would feed the poor. But later we used to keep even trotters to cook, fifteen days later. The family of Muhammad did not eat wheat bread with meat or soup to their satisfaction for three successive days.

(the slave of Ibn Azhar) I witnessed the `Id with `Umar bin Al-Khattab who said, Allah's Apostle has forbidden people to fast on the day on which you break fasting (the fasts of Ramadan) and the day on which you eat the meat of your sacrifices (the first day of `Id ul Fitr and `Id ul-Adha).

A man came to the Prophet (saws) and said: How do you fast, Messenger of Allah? The Messenger of Allah (saws) became angry at what he said.

When Umar observed this (his anger), he said: We are satisfied with Allah as Lord, with Islam as religion, and with Muhammad as Prophet. We seek refuge in Allah from the anger of Allah, and from the anger of His Apostle. Umar continued to repeat these words till his anger cooled down. He then asked: Messenger of Allah, what is the position of one who observes a perpetual fast?

He replied: May he not fast or break his fast. Musaddad said in his version: He has neither fasted nor broken his fast. The narrator, Ghaylan, doubted the actual wordings.

He asked: What is the position of one who fasts two days and does not fast one day?

He said: Is anyone able to do that? He asked: What is the position of one who fasts every second day (i.e. fasts one day and does not fasts the next day)?

He (the Prophet) said: This is the fast that David observed.

He asked: Messenger of Allah, what is the position of one who fasts one day and breaks it for two days? He replied: I wish I were given the power to observe that. Then the Messenger of Allah (saws) said: The observance of three days' fast every month and of one Ramadan to the other (i.e. the fast of Ramadan every year) is (equivalent to) a perpetual fast. I seek from Allah that fasting on the day of Arafah may atone for the sins of the preceding and the coming year, and I seek from Allah that fasting on the day of Ashura' may atone for the sins of the preceding year.

Allah's Apostle ordered (the Muslims) to fast on the day of 'Ashura', and when fasting in the month of Ramadan was prescribed, it became optional for one to fast on that day ('Ashura') or not.

The people used to fast on 'Ashura (the tenth day of the month of Muharram) before the fasting of Ramadan was made obligatory. And on that day the Ka`ba used to be covered with a cover. When Allah made the fasting of the month of Ramadan compulsory, Allah's Apostle said, "Whoever wishes to fast (on the day of 'Ashura') may do so; and whoever wishes to leave it can do so."

We kept fast for twenty-nine days along with the Prophet (saws) more often than we kept fast for thirty days.

While the Prophet was delivering a sermon on the Day of Nahr (i.e., 10th Dhul-Hijja-Day of slaughtering the sacrifice), a man got up saying, "I thought, O Allah's Apostle, such-and-such a thing was to be done before such-and-such a thing." Another man got up, saying, "O Allah's Apostle! As regards these three (acts of Hajj), thought so-and-so." The Prophet said, "Do, and there is no harm," concerning all those matters on that day. And so, on that day, whatever question he was asked, he said, "Do it, do it, and there is no harm therein."

That during the Mina days, Abu Bakr came to her, while there where two girls with her, beating drums, and the Prophet was (lying) covering himself with his garment. Abu Bakr rebuked the two girls, but the Prophet uncovered his face and said, "O Abu Bakr! Leave them, for these are the days of Id (festival)." Those days were the days of Mina-. `Aisha added, "I was being screened by the Prophet while I was watching the Ethiopians playing in the Mosque. `Umar rebuked them, but the Prophet said, "Leave them, O Bani Arfida! Play. (for) you are safe."

Sauda bint Zam`a gave up her turn to me (`Aisha), and so the Prophet used to give me (`Aisha) both my day and the day of Sauda.

The Prophet said (regarding the Verse), "A Day when all mankind will stand before the Lord of the Worlds,' (that day) they will stand, drowned in their sweat up to the middle of their ears."

The Prophet said, "We are an illiterate nation; we neither write, nor know accounts. The month is like this and this, i.e. sometimes of 29 days and sometimes of thirty days."

The Prophet (saws) said: The greatest day in Allah's sight is the day of sacrifice and next the day of resting which Isa said on the authority of Thawr is the second day. Five or six sacrificial camels were brought to the Messenger of Allah (saws) and they began to draw near to see which he would sacrifice first. When they fell down dead, he said something in a low voice, which I could not catch. So I asked: What did he say? He was told that he had said: Anyone who wants can cut off a piece.

On the days of Mina, (11th, 12th, and 13th of Dhul-Hijjah) Abu Bakr came to her while two young girls were beating the tambourine and the Prophet was lying covered with his clothes. Abu Bakr scolded them and the Prophet uncovered his face and said to Abu Bakr, "Leave them, for these days are the days of `Id and the days of Mina." `Aisha further said, "Once the Prophet was screening me and I was watching the display of black slaves in the Mosque and (`Umar) scolded them. The Prophet said, 'Leave them. O Bani Arfida! (carry on), you are safe (protected)'."

The Prophet (saws) as saying to him: Complete the recitation of the Qu'ran in one month. He said: I have more strength. He (the Prophet) said: Complete the recitation in twenty days. He again said: I have more energy. He said : Recite in fifteen days. He again said: I have more energy. He said: Recite in ten days. He again said: I have more energy. He said: Recite in seven days, do not add to it.

Abu Dawud said: The tradition narrated by Muslim is more perfect.

The Messenger of Allah (saws) offered the noon prayer on the 8th of Dhul-Hijjah (Yawm at-Tarwiyah) and dawn prayer on the 9th of Dhul-Hijjah (Yawm al-Arafah) in Mina.

On the authority of his father: The Messenger of Allah (saws) permitted the herdsmen of the camel to lapidate the the jamrahs one day and omit one day.

The Prophet used to perform I`tikaf every year in the month of Ramadan for ten days, and when it was the year of his death, he stayed in I`tikaf for twenty days.

No man embraced Islam before the day on which I embraced Islam, and no doubt, I remained for seven days as one third of the then extant Muslims.
