Yahya ibn Yahya al-Tamimi and Muhammad ibn Rumh narrated to us, both saying: Layth informed us. And Qutaybah ibn Sa'id narrated to us, saying: Layth narrated to us, from Ibn Shihab, from Abu Salamah ibn Abd al-Rahman, from A'ishah, that when the Messenger of Allah (peace and blessings be upon him) wanted to sleep while in a state of major ritual impurity (junub), he would perform the ablution (wudu) for prayer before sleeping.
