Aswad bin Yazid reported,

It was mentioned in the presence of Ayesha that Ali had been the appointed executor of the Prophet's will. She said, "When did he make a will to him? I was supporting him against my chest," or she said, "in my lap. He called for the basin, then he slumped down in my lap, and I did not even realize he had died. So when did he make a will to him?"

Sahih

عن الأسود بن يزيد قال

ذكروا عند عائشة أن عليا كان وصيا، فقالت: متى أوصى إليه؟ لقد كنت مسندته إلى صدري (أو قالت: حجري)، فدعا بالطشت، فلقد انخنث في حجري، وما شعرت أنه مات، فمتى أوصى إليه؟
