The Prophet came to Medina and saw the Jews fasting on the day of Ashura. He asked them about that. They replied, "This is a good day, the day on which Allah rescued Bani Israel from their enemy. So, Moses fasted this day." The Prophet said, "We have more claim over Moses than you." So, the Prophet fasted on that day and ordered (the Muslims) to fast (on that day).

When the Prophet came to Medina, he found (the Jews) fasting on the day of 'Ashura' (i.e. 10th of Muharram). They used to say: "This is a great day on which Allah saved Moses and drowned the folk of Pharaoh. Moses observed the fast on this day, as a sign of gratitude to Allah." The Prophet said, "I am closer to Moses than they." So, he observed the fast (on that day) and ordered the Muslims to fast on it.

When the Divine Revelation: "For those who can fast, they had a choice either fast, or feed a poor for every day," (2.184) was revealed, it was permissible for one to give a ransom and give up fasting, till the Verse succeeding it was revealed and abrogated it.

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to be cupped while he was fasting. Nafi said, "He later stopped doing that, and would not be cupped when he was fasting until he had broken the fast."

The Prophet said, "(Allah said), 'Every good deed of Adam's son is for him except fasting; it is for Me. and I shall reward (the fasting person) for it.' Verily, the smell of the mouth of a fasting person is better to Allah than the smell of musk."

When the Prophet arrived at Medina he found that the Jews observed fast on the day of 'Ashura'. They were asked the reason for the fast. They replied, "This is the day when Allah caused Moses and the children of Israel to have victory over Pharaoh, so we fast on this day as a sign of glorifying it." Allah's Apostle said, "We are closer to Moses than you." Then he ordered that fasting on this day should be observed.

That he heard Muawiya bin Abi Sufyan on the day of 'Ashura' during the year he performed the Hajj, saying on the pulpit, "O the people of Medina! Where are your Religious Scholars? I heard Allah's Apostle saying, 'This is the day of 'Ashura'. Allah has not enjoined its fasting on you but I am fasting it. You have the choice either to fast or not to fast (on this day).' "

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah, from Abu Salama ibn Abd ar-Rahman that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "The Messenger of Allah, may Allah bless him and grant him peace, used to fast for so long that we thought he would never stop fasting, and he would go without fasting for so long that we thought he would never fast again. I never saw the Messenger of Allah, may Allah bless him and grant him peace, fast for a complete month except for Ramadan, and I never saw him do more fasting in any one month than he did in Shaban.'

Yahya related to me from Malik that he had heard that the people of knowledge did not disapprove of people fasting using tooth-sticks at any hour of the day in Ramadan, whether at the beginning or the end, nor had he heard any of the people of knowledge disapproving of or forbidding the practice.

Yahya said that he heard Malik say, about fasting for six days after breaking the fast at the end of Ramadan, that he had never seen any of the people of knowledge and fiqh fasting them. He said, "I have not heard that any of our predecessors used to do that, and the people of knowledge disapprove of it and they are afraid that it might become a bida and that common and ignorant people might join to Ramadan what does not belong to it, if they were to think that the people of knowledge had given permission for that to be done and were seen doing it.

Yahya said that he heard Malik say, "I have never heard any of the people of knowledge and fiqh and those whom people take as an example forbidding fasting on the day of jumua. Fasting on it is good, and I have seen one of the people of knowledge fasting it, and it seemed to me that he was keen to do so."

Allah's Apostle used to leave fasting in a certain month till we thought that he would not fast in that month, and he used to fast in another month till we thought he would not stop fasting at all in that month. And if one wanted to see him praying at night, one could see him (in that condition), and if one wanted to see him sleeping at night, one could see him (in that condition) too.

When the Prophet arrived at Medina, he noticed that some people among the Jews used to respect Ashura' (i.e. 10th of Muharram) and fast on it. The Prophet then said, "We have more right to observe fast on this day." and ordered that fasting should be observed on it.

I asked or someone asked the Prophet (saws) about perpetual fasting. He replied: You have a duty to your family. Fast during Ramadan and the following month, and every Wednesday and Thursday. You will then have observed a perpetual fast.

[Muslim].

Sometimes Allah's Apostle would not fast (for so many days) that we thought that he would not fast that month and he sometimes used to fast (for so many days) that we thought he would not leave fasting throughout that month and (as regards his prayer and sleep at night), if you wanted to see him praying at night, you could see him praying and if you wanted to see him sleeping, you could see him sleeping.

Yahya said that he heard Malik say, "Someone who eats or drinks out of neglect or forgetfulness during a voluntary fast does not have to repeat his fast, but he should continue fasting for the rest of the day in which he eats or drinks while voluntarily fasting, and not stop fasting. Someone to whom something unexpected happens which causes him to break his fast while he is fasting voluntarily does not have to repeat his fast if he has broken it for a reason, and not simply because he decided to break his fast. Just as I do not think that someone has to repeat a voluntary prayer if he has had to stop it because of some discharge which he could prevent and which meant that he had to repeat his wudu."

Malik said, "Once a man has begun doing any of the right actions (al-amal as-saliha) such as the prayer, the fast and the hajj, or similar right actions of a voluntary nature, he should not stop until he has completed it according to what the sunna for that action is. If he says the takbir he should not stop until he has prayed two rakas. If he is fasting he should not break his fast until he has completed that day's fast. If he goes into ihram he should not return until he has completed his hajj, and if he begins doing tawaf he should not stop doing so until he has gone around the Kaba seven times. He should not stop doing any of these actions once he has started them until he has completed them, except if something happens such as illness or some other matter by which a man is excused. This is because Allah, the Blessed and Exalted, says in His Book, 'And eat and drink until the white thread becomes clear to you from the black thread of dawn, (and) then complete the fast until night-time,' (Sura 2 ayat 187), and so he must complete his fast as Allah has said. Allah, the Exalted, (also) says, 'And complete the hajj and the umra for Allah,' and so if a man were to go into ihram for a voluntary hajj having done his one obligatory hajj (on a previous occasion), he could not then stop doing his hajj having once begun it and leave ihram while in the middle of his hajj. Anyone that begins a voluntary act must complete it once he has begun doing it, just as an obligatory act must be completed . This is the best of what I have heard."

Allah's Apostle set out for Mecca in Ramadan and he fasted, and when he reached Al-Kadid, he broke his fast and the people (with him) broke their fast too. (Abu `Abdullah said, "Al-Kadid is a land covered with water between Usfan and Qudaid.")

'A'isha (Allah be pleased with her) reported that the Messenger of Allah (may peace be upon him) had ordered to observe fast (on 'Ashura) before the fasting in Ramadan was made obligatory. But when it became obligatory, then he who wished fasted on the day of Ashura, and he who wished did not observe it (on that day).

The Prophet (saws) as saying: If anyone dies when some fast is due from him (i.e. which he could not keep) his heir must fast on his behalf.

Abu Dawud said: This applies to the fast which a man vows ; and this is the opinion of Ahmad b. Hanbal.

Allah's Apostle said, "The people will remain on the right path as long as they hasten the breaking of the fast."

The Prophet (saws) said: No sadaqah is due on a horse or a slave except that given at the breaking of the fast (at the end of Ramadan).

The Messenger of Allah (saws) used to kiss me when he was fasting and when I was fasting.

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.

It was the custom among the companions of Muhammad that if any of them was fasting and the food was presented (for breaking his fast), but he slept before eating, he would not eat that night and the following day till sunset. Qais bin Sirma-al-Ansari was fasting and came to his wife at the time of Iftar (breaking one's fast) and asked her whether she had anything to eat. She replied, "No, but I would go and bring some for you." He used to do hard work during the day, so he was overwhelmed by sleep and slept. When his wife came and saw him, she said, "Disappointment for you." When it was midday on the following day, he fainted and the Prophet was informed about the whole matter and the following verses were revealed: "You are permitted To go to your wives (for sexual relation) At the night of fasting." So, they were overjoyed by it. And then Allah also revealed: "And eat and drink Until the white thread Of dawn appears to you Distinct from the black thread (of the night)." (2.187)

A man came to the Prophet and said, "O Allah's Apostle! My mother died and she ought to have fasted one month (for her missed Ramadan). Shall I fast on her behalf?" The Prophet replied in the affirmative and said, "Allah's debts have more right to be paid." In another narration a woman is reported to have said, "My sister died..." Narrated Ibn `Abbas: A woman said to the Prophet "My mother died and she had vowed to fast but she didn't fast." In another narration Ibn `Abbas is reported to have said, "A woman said to the Prophet, "My mother died while she ought to have fasted for fifteen days."

Yahya related to me from Malik from Ibn Shihab that A'isha and Hafsa, the wives of the Prophet, may Allah bless him and grant him peace, began fasting voluntarily one morning and then food was given to them and they broke their fast with it. Then the Messenger of Allah, may Allah bless him and grant him peace, came in. A'isha said, "Hafsa asked, anticipating me in speech - she took after her father Umar - 'Messenger of Allah, A'isha and I began the morning fasting voluntarily and then food was given us and we broke the fast with it.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'Fast another day in its place.' "
