Sayyiduna Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: I have been given things which were not given to any prophet. We asked: O Messenger of Allah! What are those? He (peace and blessings be upon him) said: I have been helped with awe, the keys of the earth have been given to me, my name has been kept Ahmad, the earth has been made a purifier for me, and my Ummah has been made the best of all communities.
