(V.33:6) Narrated ‘Abdullâh bin Hishâm رضي الله عنه: We were with the Prophet صلى الله عليه وسلم and he was holding the hand of ‘Umar bin Al-Khattâb. ‘Umar said to Him. "O Allâh’s Messenger! You are dearer to me than everything except my ownself." The Prophet صلى الله عليه وسلم said, "No, by Him in Whose Hand my soul is, (you will not have complete Faith) till I am dearer to you than your ownself." Then ‘Umar said to him, now, by Allâh, you are dearer to me than my ownself." The Prophet said, " Now, O ‘Umar, (now you are a believer)." Sahih Al-Bukhari, Vol.8, Hadîth No.682).
