Sahih al-Bukhari
Accepting Information Given by a Truthful Person
Chapter: The Prophet (saws) sent Az-Zubair alone to get information regarding the enemy
Narrated Jabir bin `Abdullah:
On the day of (the battle of) the Trench, the Prophet (ﷺ) called the people (to bring news about the enemy). Az-Zubair responded to his call. He called them again and Az-Zubair responded to his call again; then he called them for the third time and again Az-Zubair responded to his call whereupon the Prophet said, "Every prophet has his Hawairi (helper), and Az-Zubair is my Hawari."
