Musnad Ahmad 25:418

Ali ibn Asim narrated to us, from Yazid ibn Abi Ziyad, from Miqsam and Mujahid, from Ibn Abbas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I have been given five things that no one before me was given, and I do not say this out of pride: I have been sent to every red and black [person], and there is no red or black [person] who enters my nation except that he is one of them. And the earth has been made a place of prostration for me."
