I then asked al-Husayn ibn al-Harith: Who was the governor of Mecca? He replied: I do not know. He then met me later on and told me: He was al-Harith ibn Hatib, brother of Muhammad ibn Hatib. The governor then said: There is among you a man who is more acquainted with Allah and His Apostle than I. He witnessed this from the Messenger of Allah (ﷺ). He then pointed with his hand to a man. Al-Husayn said: I asked an old man beside me: Who is that man to whom the governor has alluded?
He said: "This is Abdullah ibn Umar, and he spoke the truth. He was more acquainted with Allah than he. He (Abdullah ibn Umar) said: For this is what the Messenger of Allah (ﷺ) commanded us (to do).
