Narrated by Sayyida Aisha (may Allah be pleased with her), she says: Sometimes the Messenger of Allah (peace and blessings be upon him) would fast so frequently that we would say he will not stop fasting, but then he would leave fasting for such a long period that we would think he will not observe voluntary fasts anymore. The Messenger of Allah (peace and blessings be upon him) did not fast an entire month except for Ramadan, and I did not see him fast in any month more than he did in Sha’ban.

(Second chain) In this, there is this addition: The Messenger of Allah (peace and blessings be upon him) would rarely leave any day of fasting in the month of Sha'ban, rather it should be said that he (peace and blessings be upon him) would fast the entire month of Sha'ban.

Sayyidah Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) did not fast in any month more than he did in Sha'ban; it was as if he fasted the entire month of Sha'ban.

Sayyidah Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) would sometimes fast so frequently that we would say he will not stop fasting now, but then he (peace and blessings be upon him) would leave fasting for such a long period that we would think he will not fast anymore. And he (peace and blessings be upon him) used to recite Surah Bani Isra'il and Surah Az-Zumar every night.

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) loved to observe voluntary fasts most in the month of Sha'ban; he (peace and blessings be upon him) would fast in this month and join it with the month of Ramadan.

Khalid bin Ma'dan says that Sayyida Aisha (may Allah be pleased with her) was asked about the voluntary fasts of the Messenger of Allah (peace and blessings be upon him). She said that he (peace and blessings be upon him) used to fast in the month of Sha'ban and gave special attention to fasting on Mondays and Thursdays.

It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him and his family) used to fast during the months of Sha'ban and Ramadan.

It is also narrated from Sayyida Umm Salama (may Allah be pleased with her), she says: I never saw the Messenger of Allah (peace and blessings be upon him) observe two consecutive months of fasting, except in the case when he (peace and blessings be upon him) would join Sha'ban with Ramadan.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that sometimes the Messenger of Allah, peace and blessings be upon him, would begin to observe voluntary fasts continuously without a break, to the extent that we would say that this year he, peace and blessings be upon him, does not intend to leave any fast. But then he, peace and blessings be upon him, would start leaving off fasting with such continuity that we would say that this year he, peace and blessings be upon him, has not kept any fast. The fasts of the month of Sha'ban were the most beloved to him, peace and blessings be upon him.

Sayyiduna Usama bin Zaid (may Allah be pleased with him) says: I said, "O Messenger of Allah! I have seen that you fast in the month of Sha'ban more than in any other month?" The Prophet (peace and blessings be upon him) said: "This is a month between Rajab and Ramadan that people are heedless of. It is a month in which the deeds of people are raised to the Lord of the worlds, and I wish that my deeds are taken up while I am fasting."
