حدثنا عمرو بن زرارة، أخبرنا إسماعيل، عن ابن عون، عن إبراهيم، عن الأسود، قال ذكروا عند عائشة أن عليا  رضى الله عنهما  كان وصيا‏.‏ فقالت متى أوصى إليه وقد كنت مسندته إلى صدري  أو قالت حجري  فدعا بالطست، فلقد انخنث في حجري، فما شعرت أنه قد مات، فمتى أوصى إليه
 Narrated Al-Aswad:                     In the presence of `Aisha some people mentioned that the Prophet had appointed `Ali by will as his successor. `Aisha said, "When did he appoint him by will? Verily when he died he was resting against my chest (or said: in my lap) and he asked for a wash-basin and then collapsed while in that state, and I could not even perceive that he had died, so when did he appoint him by will?"
