Imam Ali (as) superceded others in six

Abu Bakr, Umar, Uthman, Talha, Az-Zubayr, Saéd, Abdul Rahman ibn Oaf and some others were looking for the Prophet (MGB) in the house of Umma Salma. They found me sitting at the door. They asked me about him (MGB). I said, ‘The Prophet (MGB) will come out in a moment.’ The Prophet (MGB) came out, padded me on the shoulder and said, ‘O son of Abi Talib! I hope that you do not die. You have superseded others in sixcharacteristics. There is no one else among the Quraysh with such qualities. You are the first man who believed in God. You have been the firmest of them all in doing the orders of the Honorable the Exalted God. You have been the most loyal to your pledge to God. You have been the kindest person with the people. You are the most knowledgeable regarding judicial decrees. You have been the most fair person in equally dividing up the possessions. You are the noblest of them all to the Honorable the Exalted God.”
