Hadith 6503
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "O servants of Allah! Consider how Allah has turned away from me the abuse and cursing of the people. The Prophet Muhammad (peace and blessings be upon him) meant the Quraysh. The companions asked: O Messenger of Allah, how did this happen? The Prophet Muhammad (peace and blessings be upon him) said: They abuse 'Mudhammam' and curse 'Mudhammam' (i.e., the disbelievers of Quraysh, out of enmity, used to call the Prophet Muhammad (peace and blessings be upon him) 'Mudhammam' instead of Muhammad, so the abuse and cursing would fall upon 'Mudhammam'). I am Muhammad."
