question #3 Sahih al-Bukhari 7261, Book 95, Hadith 15 : What significance does the title ‘Hawari’ hold in Islamic tradition?

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.”
