Ikrimah said: We were with AbuHurayrah in his house when he narrated to us: The Messenger of Allah (saws) prohibited fasting on the day of Arafah at Arafah.

The Prophet (saws) said: Do not fast one day or two days just before Ramadan except in the case of a man who has been in the habit or observing a fast (on that day); and do not fast until you sight it (the moon). Then fast until you sight it. If a cloud appears on that day (i.e. 29th of Ramadan) then complete the number thirty (days) and then end the fasting: a month consists of twenty-nine days.

The Messenger of Allah (saws) prescribed the sadaqah (alms) relating to the breaking of the fast as a purification of the fasting from empty and obscene talk and as food for the poor.

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.

Ibn Abbas explained the following Qur'anic verse: "O ye who believe! fasting is prescribed for you as it was prescribed for those before you" During the lifetime of the Prophet (saws), when the people offered night prayer, they were asked to abstain from food and drink and (intercourse with) women, they kept fast till the next night. A man betrayed himself and had intercourse with his wife after he had offered the night prayer, and he did not break his fast. So Allah, the Exalted, intended to make it (fasting) easy for those who survived, thus providing a concession and utility. Allah, the Glorified, said: "Allah knoweth what ye used to do secretly among yourselves." By this Allah benefited the people and provided concession and ease to them.

I divorced my wife. I then came to Medina to sell my land that was there so that I could buy arms and fight in battle. I met a group of the Companions of the Prophet (saws).

He said: For you in the Messenger of Allah there is an excellent model. I then came to Ibn 'Abbas and asked him about the witr observed by the Prophet (saws). He said: I point to you a person who is most familiar with the witr observed by the Messenger of Allah (saws). Go to 'Aishah. While going to her I asked Hakim b. Aflah to accompany me. He refused, but I adjured him. He, therefore, went along with me. We sought permission to enter upon 'Aishah. She said: Who is this ? He said: Hakim b. Aflah. She asked: Who is with you ? He replied: Sa'd b. Hisham. She said: Hisham son of 'Amir who was killed in the Battle of Uhud. I said: Yes. She said: What a good man 'Amir was! I said: Mother of faithful, tell me about the character of the Messenger of Allah (saws). She asked: Do you not recite the Quran ? The character of Messenger of Allah (saws) was the Qur'an. I asked: Tell me about his vigil and prayer at night. She replied: Do you not recite: "O thou folded in garments" (73:1). I said: Why not ?

When the opening of this Surah was revealed, the Companions stood praying (most of the night) until their fett swelled, and the concluding verses were not revealed for twelve months from heaven. At last the concluding verses were revealed and the prayer at night became voluntary after it was obligatory. I said: Tell me about the witr of the Prophet (saws). She replied: He used to pray eight rak'ahs, sitting only during the eighth of them. Then he would stand up and pray another rak'ahs. He would sit only after the eighth and the ninth rak'ahs. He would utter salutation only after the ninth rak'ah. He would then pray two rak'ahs sitting and that made eleven rak'ahs, O my son. But when he grew old and became fleshy he observed a witr of seven, sitting only in sixth and seventh rak'ahs, and would utter salutation only after the seventh rak'ah. He would then pray two rak'ahs sitting, and that made nine rak'ahs, O my son. The Messenger of Allah (saws) would not pray through a whole night, or recite the whole Qur'an in a night or fast a complete month except in Ramadan. When he offered prayer, he would do that regularly. When he was overtaken by sleep at night, he would pray twelve rak'ahs.

The narrator said: I came to Ibn 'Abbas and narrated all this to him. By Allah, this is really a tradition.

The sunnah for one who is observing i'tikaf (in a mosque) is not to visit a patient, or to attend a funeral, or touch or embrace one's wife, or go out for anything but necessary purposes. There is no i'tikaf without fasting, and there is no i'tikaf except in a congregational mosque.
