Hisham bin Urwah narrates from his father: Sayyidah Aisha (may Allah be pleased with her) heard me talking after the Isha prayer, so she said: O Urwah, will you not let your scribe (i.e., the angels who record good deeds) rest? The Prophet Muhammad (peace be upon him) would not sleep before the Isha prayer, nor would he engage in conversation after it.
