Chapter : Pertaining to the name of Allah’s Apostle (may peace be upon him).
Jubair b. Mut’im reported on the authority of his father that he heard Allah’s Messenger (may peace be upon him) as saying: I have many names: I am Muhammad, I am Ahmad, I am al-Mahi through whom Allah obliterates unbelief, and I am Hashir (the gatherer) at whose feet people will be gathered, and I am ‘Aqib (after whom there would be none), and Allah has named him as compassionate and merciful.
