It is narrated from Umm al-Mu’minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) came to me and there was a woman with me. He (peace be upon him) asked: “Who is this?” I replied: “This is such-and-such woman, who does not sleep at night (rather, she stands in prayer).” The Messenger of Allah (peace and blessings be upon him) said: “Adopt only those deeds which you are able to do. By Allah! Allah does not tire (of giving reward), but you will tire (of performing deeds).” Umm al-Mu’minin Sayyida Aisha (may Allah be pleased with her) says: The most beloved deed to the Messenger of Allah (peace and blessings be upon him) was that which a person performed consistently.
