1340
Musnad AhmedIt was narrated that "Abdullah bin Sabu’ said: ‘Ali (رضي الله عنه) addressed us and said:
By the One Who split the seed and created the soul, this (his beard) will be soaked from this (his head, i.e., his beard would be soaked with blood from a wound in his head). He said: Tell us who he is. By Allah, we will eliminate him - or we will eliminate his family. He said: I adjure you by Allah not to kill anyone except the one who kills me. They said: If you know that, then appoint a successor. He said: No, rather I shall leave you as the Messenger of Allah (ﷺ) left you.
