On the day of Al-Ahzab (i.e. clans), Allah's Messenger (ﷺ) said, 'Who will bring us the news of the people (i.e. the clans of Quraish infidels)?" Az-Zubair said, "I." The Prophet (ﷺ) again said, "Who will bring us the news of the people?" AzZubair said, "I." The Prophet (ﷺ) again said, "Who will bring us the news of the people?" Az-Zubair said, "I." The Prophet (ﷺ) then said, "Every prophet has his Hawari (i.e. disciplespecial helper); my disciple is Az-Zubair.
Sahih al-Bukhari Book 64, Hadith 157
← Previous Hadith `Umar bin Al-Khattab came on the day of Al-Khandaq after the sun had set and he was abusing the infidels of Quraish saying, "O Allah's Messenger (ﷺ)! I was unable to offer the (`Asr) prayer till the sun was about to set." The Prophet (ﷺ) said, "By Allah, I have not offered this (i.e. `Asr) prayer." So we came down along with the Prophet (ﷺ) to Buthan where he performed ablution for the prayer and then we performed the ablution for it. Then he offered the `Asr prayer after the sun had set, and after it he offered the Maghrib prayer.

Sahih al-Bukhari Book 64, Hadith 156 Next Hadith → Allah's Messenger (ﷺ) used to say, "None has the right to be worshipped except Allah Alone (Who) honored His Warriors and made His Slave victorious, and He (Alone) defeated the (infidel) clans; so there is nothing after Him.
