Muwatta Malik, 1716

Yahya related to me from Malik from Yazid ibn Khusayfa that Urwa ibn az-Zubayr said that he heard A'isha, the wife of the Prophet, may Allah bless him and grant him peace, say, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'When a mumin is afflicted by something, even a thorn, it removes (or effaces) his wrong actions.' " Yazid did not know which of them Urwa said

Ourwa Ibn Al-Zoubair a rapporté qu'il a entendu Aicha, la femme du Prophète r (Sur lui la grâce et la paix d'Allah), dire: «L'Envoyé d'Allah r (salallahou alayhi wa salam) (Sur lui la grâce et la paix d'Allah) disait: «Tout croyant éprouvant une maladie quelconque, fût-ce même une piqûre d'épine, lui sera une sanction, ou même lui effacera ses péchés»
