From the Gospel

jesus, may allah exalt his mention, said: 'god shall take me up from the earth, and shall change the appearance of the traitor so that every one shall believe him to be me; nevertheless when he dieth an evil death, i shall abide in that dishonor for a long time in the world. but when mohammed shall come, the sacred messenger of god, that infamy shall be taken away.' (the gospel of barnabas, chapter 112)

he further said: 'adam, having sprung up upon his feet saw in the air a writing that shone like the sun, which said: 'there is only one god, and mohammed is the messenger of god.' then with fatherly affection the first man kissed those words, and rubbed his eyes and said: ''blessed be that day when thou shalt come to the world." (the gospel of barnabas, chapter 39)
