Lady Aisha (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) did not fast in any month more than he did in Sha'ban. He would fast for the entire days of Sha'ban. He used to say: "Do those deeds which you are able to do, for Allah does not tire (of giving reward) until you tire (of doing deeds) yourselves." The Prophet (peace and blessings be upon him) liked that prayer the most which was performed regularly, even if it was little. Thus, whenever the Prophet (peace and blessings be upon him) started a prayer, he would always continue it.
