Harmalah ibn Yahya narrated to me, saying: Abdullah ibn Wahb informed us, saying: Haywah informed us, saying: Ibn al-Had narrated to us, from Abu Bakr ibn Hazm, from Amrah, from Aishah, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: "No affliction befalls a believer—even a thorn that pricks him—except that Allah writes for him a good deed thereby, or erases from him a sin thereby."
