"I asked Aishah about the Prophet's fasting.' She said: 'He would fast until we said: "He has fasted" and he would abstain from fasting until we said: "He has abstained from fasting." (She said:) 'The Messenger of Allah did not fast an entire month except Ramadan.'"

Anas bin Malik was asked about the Prophet's fasting and he said: "He would fast during a month until we thought that he did not want to abstain from fasting during any of it. And, he would not fast during a month until we thought that he did not want to fast during any of it. (There was no time) that I wanted to see if he was performing Salat during the night, except that I would see him praying, nor to see him sleeping, except that I would see him sleeping."

The Messenger of Allah said: "The most virtuous fast is the fast of my brother Dawud. He would fast a day, and not fast (the next) day. He would not flee at the time of engagement (with the enemy)."

"I witnessed Umar bin Al-Khattab on the Day of Nahr beginning with the Salat before the Khutbah. Then he said: 'I heard the Messenger of Allah prohibit fasting on these two days. As for the Day of Fitr, then it is for you to take a break from your fasting, and a celebration for the Muslims. As for the Day of Adha, then eat from the flesh that you have sacrificed.'"

"the Messenger of Allah was cupped while he was fasting and in Ihram."

"Aishah and Umm Salamah, the wives of the Prophet informed me that the Prophet would find that it was Fajr while he was Junub from (relations with) his wives, then he would perform Ghusl and fast."

The Prophet said: "When one of you is invited to eat then let him respond, if he is fasting then let him pray." Meaning: supplicate.

"We were on a journey with the Messenger of Allah during the month of Ramadan. No one objected to the fast of the one fasting nor the fast breaking of the one who broke his fast."

"The Prophet would kiss during the month of fasting."

the Prophet said: "Whoever did not decide to fast before Fajr then there is no fast for him."

the Messenger of Allah said: "The most virtuous fasting after the month of Ramadan is Allah's month Al-Muharram."

"A man asked Ali: "Which month do you order me to fast after the month of Ramadan?' He said to him, 'I have not heard anyone ask this except for a man whom I heard asking the Messenger of Allah while I was sitting with him. He said: "O Messenger of Allah! Which month do you order me to fast after the month of Ramadan?" He said: "If you will fast after the month of Ramadan, then fast Al-Muharram, for indeed it is Allah's month in which there is a day that Allah accepted the repentance of a people, and in which He accepts the repentance of other people."

"The Messenger of Allah would fasting during the beginning of every month for three days, and Friday was the least of the days that he did not fast."

the Messenger of Allah said: "None of you should fast on Friday unless he fasts before it, or he fasts after it."

"The Prophet used to try to fast on Mondays and Thursdays."

"The Messenger of Allah would fast Saturdays, Sundays, and Mondays in one months, and Tuesdays, Wednesdays and Thursdays in the next month."

the Prophet said: "Fast the Day of Ashura, for indeed I anticipate that Allah will forgive (the sins of) the year before it."

"The Messenger of Allah said: 'Whoever fasts three days in every month, then that is (similar to) fasting every day.' Then Allah Mighty and Sublime is He, attested to that in His Book, by revealing: Whoever brings a good deed, shall have ten times the like thereof. So a day is like ten."

The Prophet said: "The cupper and the one cupped have broke the fast."
