It was narrated from Malik bin Mighwal that Talhah bin Musarrif said:
“I said to Abdullah bin Abu Awfa: 'Did the Messenger of Allah ﷺ make a will concerning anything?' He said: 'No.' I said: 'How come he told the Muslims to make wills?' He said: 'He enjoined (them to adhere to) the book of Allah (Subhanahu-wa-Taala).” Malik said: “Talhah bin Musarrif said: 'Huzail bin Shurahbil said: “Abu Bakr was granted leadership according to the will of Messenger of Allah ﷺ?” (Rather) Abu Bakr wished that the found a covenant (in that regard) from Messenger of Allah ﷺ, so he could fetter his nose with a (camel's) nose ring.”
