أحمد بن إسحاق السرخسي

Aḥmad ibn Isḥāq al-Sarakhsī related to us. He said: My father related to us. He said: Al-Mughīth ibn Budayl related to us, from Khārija, from Abū Ḥanīfa, from Abū Isḥāq al-Hamdānī, from al-Aswad, from ʿĀʾisha, may God be pleased with her: The Prophet of God, God bless him and grant him peace, would become ritually impure through intercourse with his wife, then sleep without performing ablution until he took the full ritual bath late in the night.
