Abdullah bin Shaqiq says that I asked Umm al-Mu'mineen Sayyida Aisha Siddiqa (may Allah be pleased with her) about the fasts of the Prophet (peace and blessings be upon him), so she said: When he (peace be upon him) would fast, we would say that now he will continue fasting, and when he would break his fast, we would say that now he will continue not fasting. And since he came to Madinah, apart from the month of Ramadan, he did not fast for any complete month.

It was asked from Sayyiduna Anas bin Malik (may Allah be pleased with him) about the fasting of the Prophet (peace and blessings be upon him), so he replied: The Prophet (peace and blessings be upon him) would fast so much in a month that we would say he will not break his fast, and when he would break his fast, we would say he will not fast at all from it. And if you wished to see him praying at night, you would certainly be able to see him praying, and if you wished to see him sleeping, you would certainly be able to see him sleeping.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both), he says that the Noble Prophet (peace and blessings be upon him) would fast to such an extent that we would say he will not leave a single day of this month without fasting, and (at times, for many days) he would not fast, to the extent that we would say he does not wish to fast any day of this month. And since he arrived in (Madina Munawwara), he did not fast the complete month in any month except Ramadan.

It is narrated from Umm al-Mu'minin Sayyida Umm Salamah (may Allah be pleased with her), she says: I never saw the Prophet (peace be upon him) fasting two consecutive months except for Sha'ban and Ramadan. Imam Abu Isa al-Tirmidhi (may Allah have mercy on him) says: This chain is authentic, and the narrator has said it exactly as «عن أبي سلمة عن أم سلمة» . This hadith has been narrated by more than one person through the way of «عن أبي سلمة عن عائشة عن النبي صلى الله عليه وسلم» , and it is also possible that Abu Salamah bin Abdur Rahman narrated this hadith from «عن عائشة وأم سلمة رضي الله عنهما عن النبي صلى الله عليه وسلم» .

It is narrated from Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she says: I did not see the Messenger of Allah (peace and blessings be upon him) fasting in any month more than in Sha'ban. He would fast in most of Sha'ban, rather he would fast the entire month of Sha'ban except for a little.

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings be upon him) used to fast three days from the beginning of every month, and very rarely did he not fast on Friday.

Yazid al-Rashk says that I heard from Mu’adhah, she said: I asked Umm al-Mu’minin Sayyidah Aisha Siddiqa (may Allah be pleased with her): Did the Messenger of Allah (peace and blessings be upon him) fast three days every month? She replied: Yes! I asked: On which days did he (peace and blessings be upon him) fast? She said: He did not pay attention to any specific day, rather he would fast on any day. Imam Tirmidhi (may Allah have mercy on him) says that by Yazid al-Rashk, Yazid al-Dubai is meant. And he is trustworthy; from him Shu’bah, Abdul Warith bin Sa’id, Hammad bin Zaid, Ismail bin Ibrahim, and many other Imams have narrated. By Yazid al-Qasim and Yazid al-Qassam, the same person is meant. In the language of the people of Basra, Rashk means one who distributes a lot.

It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) used to fast on Saturday, Sunday, and Monday in one month, and in the next month he used to fast on Tuesday, Wednesday, and Thursday.

It is narrated from Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she states that the Messenger of Allah (peace and blessings be upon him) used to especially observe fasting on Mondays and Thursdays.
