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. If anyone pays it before the prayer (of 'Id), it will be accepted as zakat. If anyone pays it after the prayer, that will be a sadaqah like other sadaqahs (alms).

The Prophet (saws) came to visit Sa'd ibn Ubaydah, and he brought bread and olive oil, and he ate (them). Them). Then the Prophet (saws) said: May the fasting (men) break their fast with you, and the pious eat your food, and the angels pray for blessing on you.

I never saw the Prophet seeking to fast on a day that he favored more than another except this day, the day of 'Ashura', and this month, meaning the month of Ramadan.

The Prophet (saws) said: if one has a sudden attack of vomiting while one is fasting, no atonement is required of him, but if he vomits intentionally he must make atonement.

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.

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.

Abu Dawud said: Malik said: This is a false (tradition).

The Messenger of Allah (saws) said: (The reward of) prayer, fasting and remembrance of Allah is enhanced seven hundred times over (the reward of) spending in Allah's path.

The Prophet said, "If somebody eats or drinks forgetfully then he should complete his fast, for what he has eaten or drunk, has been given to him by Allah."

Allah's Apostle said, "Whoever observes fasts during the month of Ramadan out of sincere faith, and hoping to attain Allah's rewards, then all his past sins will be forgiven."

At times Allah's Apostle used to get up in the morning in the state of Janaba after having sexual relations with his wives. He would then take a bath and fast.

Sometimes I missed some days of Ramadan, but could not fast in lieu of them except in the month of Sha'ban." Said Yahya, a sub-narrator, "She used to be busy serving the Prophet ."

I have seen the Messenger of Allah (saws) using a tooth-stick while he was fasting. Musaddad added in his version: "more often than I could count."

'A'isha (Allah be pleased with her) reported that Allah's Messenger (may peace be upon him) kissed (his wives) during Ramadan while observing fast.

'A'isha (Allah be pleased with her) said that the Prophet (may peace be upon him) forbade to observe fast on two days-the day of Fitr and the day of Adha.

Allah's Apostle said, "The month (can be) 29 nights (i.e. days), and do not fast till you see the moon, and if the sky is overcast, then complete Sha'ban as thirty days."

A hadith like this has been reported from the Apostle of Allah (may peace be upon him) by 'Abd al-Malik with the same chain of transmitters in connection with fast.

Hunaydah al-Khuza'i reported on the authority of her mother who said: I entered upon Umm Salamah and asked her about fasting. She said: The Messenger of Allah (saws) used to command me to fast three days every month beginning with Monday or Thursday.

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.

The Messenger of Allah (saws) made a brotherhood between two men, one of whom was killed (in Allah's path), and a week or thereabouts later the other died, and we prayed at his funeral). The Messenger of Allah (saws) asked: What did you say? We replied: We prayed for him and said: O Allah, forgive him, and join him to his companion. The Messenger of Allah (saws) said: What about his prayers since the time the other died, and his fasting since the time the other died--the narrator Shu'bah doubted the words, "his fasting--and his deeds since the time the other died. The distance between them is just like the distance between heaven and earth.
