It was narrated that Jabir said:
"The Messenger of Allah said on the Day of Quraizah: 'Who will bring us news of the people?' Zubair said: 'I will.' The Prophet said: 'Who will bring us news of the people?' Zubair said: 'I will,' three times. Every Prophet has a Hawari (sincere supporter or disciple) and my Hawari is Zubair.'"
