"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 Messenger of Allah said: "Do not fast on Saturday except for what has been made obligatory upon you (by Allah). If one of you does not find but a grape peal or a tree's twig, then let him chew 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 Messenger of Allah said: "Deeds are presented on Monday and Thursday, and I love that my deeds be presented while I am fasting."

"I asked - or; the Prophet was asked - about fasting daily. So he said: 'Your family has a right over you.' Then he said: 'Fast Ramadan and that which is after it, and every Wednesday and Thursday. If you do that, then you will have fasted daily, as well as broken (the fast).'"

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

"The Prophet broke (the fast) of Arafah, Umm Fadl sent him some milk to drink."

"Ibn Umar was asked about fasting (the Day of) Arafah (at Arafat). He said: 'I performed Hajj with the Prophet, and he did not fast it, and with Abu Bakr, and he did not fast it, and with Umar, and he did not fast it, and with Uthman, and he did not fast it. I do no fast it, nor order it nor forbid it."

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

"Ashura was a day that the Quraish used to fast during Jahiliyyah, and the Messenger of Allah used to fast it. But when (the fast of) Ramadan became obligatory, the Ramadan was the required and Ashura was left. So whoever wanted to, he fasted it, and whoever wanted to, he left it."

"I met up with Ibn Abbas while he was reclining on his Rida at the Zamzam (well). So I said: 'Inform me about the Day of Ashura. On which day is it fasted?' He said: 'When you see the crescent of Al-Muharram, then count, then fast on the morning of the ninth day.'" He said: 'I said: Is this how Muhammad fasted it?' He said: 'Yes.'"

"The Messenger of Allah ordered fasting the tenth day for the Day of Ashura."

"I did not see the Prophet fasting at all during the ten."

the Messenger of Allah said: "There are no days in which righteous deeds are more beloved to Allah than those ten days." They said: "O Messenger of Allah! Not even Jihad in Allah Cause?" The Messenger of Allah said: "Not even Jihad in Allah's Cause, unless a man were to out with his self and his wealth and not return from that with anything."

the Prophet said: "There are no days more beloved to Allah that He be worshipped in them than the ten days of Dhul-Hijjah, fasting every day of them is the equivalent of fasting a year, and standing every night of them (in prayer) is the equivalent of standing on the Night of Qadr."

the Messenger of Allah said: "Whoever fasts Ramadan, then follows it with six from Shawwal, then that is (equal in reward) to fasting everyday."

"The Messenger of Allah took a covenant from me for three: To not sleep except after performing Witr, to fast three days of every month, and to perform the Duha prayer."
