Sahih Muslim 1162 b

Abu Qatada al-Ansari (Allah be pleased with him) reported that the Messenger of Allah (may peace be upon him) was asked about his fasting. The Messenger of Allah (may peace be upon him) felt annoyed. Thereupon 'Umar (Allah be pleased with him) said:

We are pleased with Allah as the Lord, with Islam as our Code of Life, with Muhammad as the Messenger and with our pledge (to you for willing and cheerful submission) as a (sacred) commitment. He was then asked about perpetual fasting, whereupon he said: He neither fasted nor did he break it, or he did not fast and he did not break it. He was then asked about fasting for two days and breaking one day. He (the Holy Prophet) said: And who has strength enough to do it? He was asked about fasting for a day and breaking for two days, whereupon he said: May Allah bestow upon us strength to do it. He was then asked about fasting for a day and breaking on the other, whereupon he said: That is the fasting of my brother David (peace be upon him). He was then asked about fasting on Monday, whereupon he said: It was the day on which I was born. on which I was commissioned with prophethood or revelation was sent to me, (and he further) said: Three days' fasting every month and of the whole of Ramadan every year is a perpetual fast. He was asked about fasting on the day of 'Arafa (9th of Dhu'I-Hijja), whereupon he said: It expiates the sins of the preceding year and the coming year. He was asked about fasting on the day of 'Ashura (10th of Muharram), whereupon be said: It expiates the sins of the preceding year. (Imam Muslim said that in this hadith there is a) narration of Imam Shu'ba that he was asked about fasting on Monday and Thursday, but we (Imam Muslim) did not mention Thursday for we found it as an error (in reporting).

Sahih al-Bukhari 4276

Narrated Ibn `Abbas:

The Prophet left Medina (for Mecca) in the company of ten-thousand (Muslim warriors) in (the month of) Ramadan, and that was eight and a half years after his migration to Medina. He and the Muslims who were with him, proceeded on their way to Mecca. He was fasting and they were fasting, but when they reached a place called Al-Kadid which was a place of water between 'Usfan and Kudaid, he broke his fast and so did they. (Az-Zuhri said, "One should take the last action of Allah's Apostle and leave his early action (while taking a verdict.")

'A'isha, the Mother of the Believers (Allah be pleased with her), reported:

The Apostle of Allah (may peace be upon him) came to me one day and said: Is there anything with you (to eat)? I said: No. Thereupon he said: I shall then be fasting.

'A'isha, the Mother of the Believers (Allah be pleased with her), reported that the Messenger of Allah (may peace be upon him) used to fast (so continuously) that we said that he would not break, and did not fast at all till we said that he would not fast. And I did not see the Messenger of Allah (may peace be upon him) completing the fast of a month, but that of Ramadan, and I did not see him fasting more in any other month than that of Sha'ban.

Narrated Abu Hurairah:

"It was said, 'O Messenger of Allah, what equals Jihad?' He said: 'Verily, you (people) are not capable of it.' So they repeated it to him two or three times, each time he said, 'You (people) are not capable of it.' Then he said the third time: 'The example of the Mujahid in the path of Allah is like the one who fasts and stands (in prayer) and does not slacken from Salat, nor fasting, until the Mujahid in the cause of Allah returns.'"

There are narrations on this topic from Ash-Shifa', 'Abdullah bin Hubshi, Abu Musa', Abu Sa'eed, Umm Malik Al-Bahziyyah, and Anas.

It was narrated from 'Aishah, the mother of the Believers, that the Prophet used to come to her when he was fasting and say:
"Do you have anything this morning that you can give me to eat?" we would say no, and he would say: "I am fasting." Then after that he came and she said: "I have been given a gift." He said: "What is it?" she said: "Hais." He said: "I started the day fasting," but then he ate.

Narrated Shaqiq:

that he had heard Hudhaifa saying, "Once I was sitting with `Umar and he said, 'Who amongst you remembers the statement of Allah's Apostle about the afflictions?' I said, 'I know it as the Prophet had said it.' `Umar said, 'No doubt you are bold.' I said, 'The afflictions caused for a man by his wife, money, children and neighbor are expiated by his prayers, fasting, charity and by enjoining (what is good) and forbidding (what is evil).' `Umar said, 'I did not mean that but I asked about that affliction which will spread like the waves of the sea.' I (Hudhaifa) said, 'O leader of the faithful believers! You need not be afraid of it as there is a closed door between you and it.' `Umar asked, Will the door be broken or opened?' I replied, 'It will be broken.' `Umar said, 'Then it will never be closed again.' I was asked whether `Umar knew that door. I replied that he knew it as one knows that there will be night before the tomorrow morning. I narrated a Hadith that was free from any misstatement" The subnarrator added that they deputized Masruq to ask Hudhaifa (about the door). Hudhaifa said, "The door was `Umar himself."

Narrated Aisha:

During the Pre-lslamic Period of ignorance the Quraish used to observe fasting on the day of 'Ashura', and the Prophet himself used to observe fasting on it too. But when he came to Medina, he fasted on that day and ordered the Muslims to fast on it. When (the order of compulsory fasting in ) Ramadan was revealed, fasting in Ramadan became an obligation, and fasting on 'Ashura' was given up, and who ever wished to fast (on it) did so, and whoever did not wish to fast on it, did not fast.

Narrated `Aisha:

'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.

Narrated Abu Sa`id Al-Khudri:

While the Prophet was distributing (war booty etc.) one day, Dhul Khawaisira, a man from the tribe of Bani Tamim, said, "O Allah's Apostle! Act justly." The Prophets said, "Woe to you! Who else would act justly if I did not act justly?" `Umar said (to the Prophet ), "Allow me to chop his neck off." The Prophet said, "No, for he has companions (who are apparently so pious that) if anyone of (you compares his prayer with) their prayer, he will consider his prayer inferior to theirs, and similarly his fasting inferior to theirs, but they will desert Islam (go out of religion) as an arrow goes through the victim's body (games etc.) in which case if its Nasl is examined nothing will be seen thereon, and if its Nady is examined, nothing will be seen thereon, and if its Qudhadh is examined, nothing will be seen thereon, for the arrow has gone out too fast even for the excretions and blood to smear over it. Such people will come out at the time of difference among the (Muslim) people and the sign by which they will be recognized, will be a man whose one of the two hands will look like the breast of a woman or a lump of flesh moving loosely." Abu Sa`id added, "I testify that I heard that from the Prophet and also testify that I was with `Ali when `Ali fought against those people. The man described by the Prophet was searched for among the killed, and was found, and he was exactly as the Prophet had described him." (See Hadith No. 807, Vol. 4)

Abu Hurairah said:
"The Messenger of Allah said: 'Allah, the Mighty and sublime, said: Every deed of the son of Adam is for him, except fasting; it is for me and I shall reward for it. Fasting is a shield. If any one of you is observing a fast, let him not utte obscene a fast, let him not utter obscene talk or raise his voice in anger, and if anyone insults him or wants to fight, let him say: I am a person who is fasting. By the One in Whose hand is the soul of Muhammad, the smell coming from the mouth of the fasting person is better before Allah than the fragrance of musk." ' (Sahih) This Hadith was narrated from Abu Hurairah by Saeed bin Al-Musayyab.

It was narrated from Abu Nawfal bin Abi 'Aqrab, from his father, that he asked the Prophet about fasting and he said:
"Fast one day of each month." He asked him for more, saying: "May my father and mother be ransomed for you, I am able." He said: "Fast two days of each month." He said" May my father and mother be sacrificed for you, O Messenger of Allah, I am able." The Messenger of Allah said: "I am able, I am able." He did not want to increase it, but when I insisted, the Messenger of Allah said: "Fast three days of each month." (Sahih) The end of what the Shaikh had about fasting, all praise is due to Allah the Lord of the worlds.

Narrated Abu Huraira:

Allah's Apostle forbade Al-Wisal in fasting. So, one of the Muslims said to him, "But you practice Al- Wisal. O Allah's Apostle!" The Prophet replied, "Who amongst you is similar to me? I am given food and drink during my sleep by my Lord." So, when the people refused to stop Al-Wisal (fasting continuously), the Prophet fasted day and night continuously along with them for a day and then another day and then they saw the crescent moon (of the month of Shawwal). The Prophet said to them (angrily), "If It (the crescent) had not appeared, I would have made you fast for a longer period." That was as a punishment for them when they refused to stop (practicing Al-Wisal).
