Silsilat al-Ahadith al-Sahihah

Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "I have been given such things which were not given to any prophet before me." We asked: O Messenger of Allah! What are those? He (peace and blessings be upon him) said: "(My) awe has been cast (over people) to help me, I have been granted the keys of the earth, my name has been kept Ahmad, the earth has been made a purifier for me, and my Ummah has been declared the best Ummah."
