It is narrated from Sayyiduna Abu Salamah bin Abdur Rahman that he asked Sayyidah Aisha (may Allah be pleased with her) about the manner of the fasts of the Messenger of Allah (peace and blessings be upon him), so she replied: He would fast (so continuously) that we would say he will not leave fasting, and then he would stop fasting to the extent that we would begin to say he will not fast now. He used to fast the entire month of Sha’ban or most of Sha’ban.

Hazrat Humaid narrates that it was asked from Sayyiduna Anas bin Malik (may Allah be pleased with him) about the fasts of the Prophet Muhammad (peace and blessings be upon him), so he said that the Prophet would keep fasting in a month to such an extent that we would think he does not want to leave any day without fasting in that month. And then he would stop fasting in a month to such an extent that we would think he will not fast at all in that month. And you could see him praying at any part of the night if you wished, and if you wished, you could see him sleeping. This narration is from Isma'il bin Ja'far. And in the narration of Khalid bin Harith, it is mentioned that Sayyiduna Anas (may Allah be pleased with him) was asked about the voluntary prayers and fasts of the Prophet Muhammad (peace and blessings be upon him).

Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to fast to such an extent that I would think he would always fast, and he would stop fasting to such an extent that I would say he will not fast. And he used to fast most often in the month of Sha'ban.

Sayyiduna Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in Paradise there are such lofty chambers that their outer parts can be seen from inside and their inner parts can be seen from outside." Then a Bedouin stood up and asked, "O Messenger of Allah, for whom are these lofty chambers?" The Prophet (peace and blessings be upon him) replied: "They are for the one who speaks pure and sweet words, feeds the hungry, continuously fasts, and offers voluntary prayers at night for the pleasure of Allah while people are asleep."

Sayyiduna Abu Malik Ash'ari (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, in Paradise there are lofty chambers whose exterior can be seen from their interior and whose interior can be seen from their exterior. Allah Almighty has prepared these chambers for the person who feeds others, speaks gently, fasts regularly, and prays at night while people are asleep."

The grandmother of Habib bin Zaid, Sayyida Umm Ammarah bint Ka'b (may Allah be pleased with her), narrates that the Messenger of Allah (peace and blessings be upon him) came to her while she was fasting. She presented food to him, so the Prophet (peace and blessings be upon him) said: "Come and eat." She replied that she was fasting. The Noble Prophet (peace and blessings be upon him) said: "When food is eaten in the presence of a fasting person, the angels pray for his forgiveness."

From the chain of narration of Ali bin Khushram, it is narrated from Sayyidah Umm Ammarah bint Ka'b (may Allah be pleased with her) similar to the above, and in it this addition is mentioned: "Until they finish eating, or they finish the food." Imam Shu'bah is in doubt as to which words were said.

It is narrated from Sayyidah Umm ‘Ammarah bint Ka‘b (may Allah be pleased with her) that the Prophet (peace and blessings of Allah be upon him) said: "When those who are not fasting eat in the presence of a fasting person, the angels pray for him until the evening."
