مسند أحمد

It was narrated that Zirr bin Hubaish said: Ibn Jurmooz asked for permission to enter upon ‘Ali (رضي الله عنه). He said: Who is this? They said: Jurmooz is asking for permission to enter upon you. He said: Let him in; let the killer of Az-Zubair enter the Fire, I heard the Messenger of Allah (ﷺ) say: “Every Prophet (ﷺ) has a disciple and my disciple is Az-Zubair.”
