It is narrated from Umm al-Mu'minin Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever has a habit of praying at night, and then sleep overcomes him, Allah Almighty writes for him the reward of that night's prayer, and his sleep becomes a charity for him from Allah."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Abu Ja'far al-Razi narrated this hadith from Muhammad bin al-Munkadir, from Sa'id bin Jubayr, from al-Aswad bin Yazid, from Sayyidah Aishah (may Allah be pleased with her)." And Imam Malik (may Allah have mercy on him) narrated it from Muhammad bin al-Munkadir, from Sa'id bin Jubayr, from Sayyidah Aishah (may Allah be pleased with her).
