Lady 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 of the year more than he fasted in the month of Sha'ban; he (peace be upon him) used to fast the entire month.

A narration similar to the above is reported from Sayyidah Aisha (may Allah be pleased with her). In it, there is this addition that the Prophet (peace be upon him) said: "Do as much as you are able, for Allah does not tire (of giving reward) until you tire (of performing deeds)." And the (supererogatory) prayer most beloved to him was that which was performed regularly, even if it was little. And his blessed practice was that whenever he performed a prayer, he would always continue to perform it.
