Musannaf Ibn Abi Shaybah

Aswad narrates that it was mentioned in the presence of Hazrat Aisha (may Allah be pleased with her) that Hazrat Ali (may Allah be pleased with him) was the executor (wasi) of the Prophet Muhammad (peace and blessings be upon him). She said, "When did the Prophet (peace and blessings be upon him) make him the executor? I had the Prophet (peace and blessings be upon him) resting in my lap when his blessed body became limp and he passed away, so when did he make him the executor?"
