Narrated Jabir [may Allah be pleased with him]:
that the Messenger of Allah (ﷺ) said: Indeed, every Prophet has a Hawari and, [indeed], my Hawari is Az-Zubair [bin Al-'Awwam]. And Abu Na'im added in it: On the Day of Al-Ahzab, he (ﷺ) said: 'Who will bring us news about their party?' Az-Zubair said: 'I will.' He said it three times. Az-Zubair said (each time): 'I will.'
