Narrated Ibn Umar: Umar said: I shall not appoint a successor, for the Messenger of Allah ﷺ did not appoint a successor. If I appoint a successor (I can do so), for Abu Bakr had appointed a successor. He Ibn Umar) said: I swear by Allah, he did not mention (anyone) but the Messenger of Allah ﷺ and Abu Bakr. So I learnt he would not equate anyone with the Messenger of Allah ﷺ, for he did not appoint any successor.
