Muhammad is no more than a Messenger: many were the Messengers that passed away before him. If he died or were slain, will ye then turn back on your heels? If any did turn back on his heels not the least harm will he do to Allah; but Allah (on the other hand) will swiftly reward those who (serve) him with gratitude.[Qur'an 3:144]

Narrated 'Umar(RA): I heard the Prophet(PBUH) saying, "Do not exaggerate in praising me as the Christians praised the son of Mary, for I am only a Slave. So, call me the Slave of Allah and His Apostle."
