مسند أحمد

It was narrated that Zirr bin Hubaish said: Ibn Jurmooz asked for permission to enter upon ‘Ali when I was with him, ‘Ali (رضي الله عنه) said: Give the killer of Ibn Safiyyah the tidings of Hell. Then `Ali (رضي الله عنه) said: I heard the Messenger of Allah (ﷺ) say: `Every Prophet (ﷺ) has a disciple and my disciple is Az-Zubair.` I heard Sufyan say: A disciple is a supporter.
