Mukhtasar Muslim

Abu Musa Ash'ari (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) used to mention several names of himself to us, and he (peace be upon him) said: I am Muhammad (peace be upon him), and Ahmad, and Muqaffi (that is, Aqib), and Hashir, and the Prophet of Repentance, and the Prophet of Mercy (because repentance and mercy have been brought by him, peace be upon him).
