Narated By Sa’d ibn AbuWaqqas : On the day of the conquest of Mecca, Abdullah ibn Sa’d ibn AbuSarh hid himself with Uthman ibn Affan.
He brought him and made him stand before the Prophet (PBUH), and said: Accept the allegiance of Abdullah, Apostle of Allah! He raised his head and looked at him three times, refusing him each time, but accepted his allegiance after the third time.
Then turning to his companions, he said: Was not there a wise man among you who would stand up to him when he saw that I had withheld my hand from accepting his allegiance, and kill him?
They said: We did not know what you had in your heart, Apostle of Allah! Why did you not give us a signal with your eye?
He said: It is not advisable for a Prophet to play deceptive tricks with the eyes.
