Narrated Jubair bin Mut`im: I heard Allah's Messenger saying, 'I have several names: I am Muhammad and I am Ahmad, and I am Al- Mahi with whom Allah obliterates Kufr (disbelief), and I am Al-Hashir (gatherer) at whose feet (i.e. behind whom) the people will be gathered (on the Day of Resurrection), and I am Al-Aqib (i.e. who succeeds the other prophets in bringing about good).
Mujahid said the meaning of «من أنصاري إلى الله» is: Who goes towards Allah along with me? And Ibn Abbas (may Allah be pleased with them both) said «مرصوص» means firmly joined, attached, and others said: joined together with lead.
