It is narrated from Sayyiduna Abdullah bin Hisham (may Allah be pleased with him) that he said: "We were with the Prophet (peace and blessings be upon him) and he (peace and blessings be upon him) was holding the hand of Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). Sayyiduna Umar (may Allah be pleased with him) said: 'O Messenger of Allah! By Allah, you are certainly dearer to me than everything except my own self.' At that he (peace and blessings be upon him) said: 'No, by the One in whose hand is my soul! (Your faith cannot be complete) until I am dearer to you than your own self.' Then Sayyiduna Umar (may Allah be pleased with him) said: 'Now you are dearer to me than my own self.' At that the Messenger of Allah (peace and blessings be upon him) said: 'Now, O Umar! (Now your faith is complete).'"
