Simak bin Harb narrated: "A person from the offspring of Umm Hani narrated to me - I met one of the most virtuous among them, and his name was Ja'dah, and Umm Hani was his grandmother - he narrated to me from his grandmother that the Messenger of Allah (ﷺ) entered upon her and asked for some drink, and he drank. Then he offered it to her and she drank it. Then she said: "O Messenger of Allah! I was fasting." So the Messenger of Allah (ﷺ) said: "The one fasting a voluntary fast is the trustee for himself; if he wishes he fasts, and if he wishes he breaks." Shu'bah (one of the narrators) said: "I said to him (Ja'dah), 'Did you hear this from Umm Hani?' He said: 'No Abu Salih and our family informed us of it from Umm Hani.'"

Aishah, the Mother of the Believers, narrated: "The Messenger of Allah (ﷺ) visited me one day and said: 'Do you have anything (to eat)?'" She said: "I said: 'No.' He said: 'Then I am fasting.'"

(Another chain, a Hadith similar to no. 736) for that, from Aishah, : from the Prophet.

Aishah narrated: "I could not find the Messenger of Allah (ﷺ) one night. So I left and found him at Al-Baqi. He said: 'Did you fear that you had been wronged by Allah and His Messenger?' I said: 'O Messenger of Allah! I thought that you had gone to one of your wives.' So he said: 'Indeed Allah, Mighty and Sublime is He, descends to the lowest Heavens during the night of the middle of Sha'ban, to grant forgiveness to more than the number of hairs on the sheep of (Banu) Kalb.'"

Abdullah bin Busr narrated from his sister that : the Messenger of Allah (ﷺ) 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."

Ubaidullah (bin Muslim) Al-Qurashi narrated from his father who said: "I asked - or; the Prophet (ﷺ) 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).'"

Abu Qatadah narrated that : the Prophet (ﷺ) 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."

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

Ibn Abi Najib narrated from his father who said: "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."

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

Aishah narrated: "Ashura was a day that the Quraish used to fast during Jahiliyyah, and the Messenger of Allah (ﷺ) 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."

Al-Hakam bin Al-Arfaj said: "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.'"

Aishah narrated: "I did not see the Prophet (ﷺ) fasting at all during the ten."

Ibn Abbas narrated that : the Messenger of Allah (ﷺ) 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 (ﷺ) 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."

Abu Hurairah narrated that : the Prophet (ﷺ) 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."

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

Abu Hurairah narrated: "The Messenger of Allah (ﷺ) 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."

Abu Dharr narrated that : the Messenger of Allah (ﷺ) said: "O Abu Dharr! When you fast three days out of a month, then fast the thirteenth, fourteenth, and fifteenth."

Abu Dharr narrated: "The Messenger of Allah (ﷺ) 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."

Yazid Ar-Rishk said: "I heard Mu'adhah saying to Aishah: 'Did the Messenger of Allah (ﷺ) fast three days of every month?' She replied in the affirmative. So she said: 'Which of them would he fast?' She said: 'Which of them he would fast was not noticeable.'"
