Abu Salamah bin Abdur Rahman narrates: I went to the service of Sayyidah Aisha (may Allah be pleased with her). I said to her: Mother! Tell me about the night voluntary prayer of the Prophet (peace and blessings be upon him) and about his voluntary fasts. Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) said: The Prophet (peace and blessings be upon him) used to observe voluntary fasts to such an extent that we would think he would continue to fast without break, but then he would abandon voluntary fasting to such an extent that we would think he would not fast any more voluntary fasts. I did not see the Prophet (peace and blessings be upon him) fasting in any month more than in the month of Sha'ban. The Prophet (peace and blessings be upon him) used to fast almost the entire month, only a few days he would not fast in Sha'ban, and in Ramadan and outside of Ramadan, the night prayer of the Prophet (peace and blessings be upon him) used to be thirteen rak'ahs, in which the two rak'ahs (Sunnah) of Fajr were also included.
