"Worship none but Allah. Verily I (Muhammad) am unto you from Him a warner and a bringer of glad tidings". Holy Quran 11:2
[Jesus] said, "Indeed, I am the servant of Allah . He has given me the Scripture and made me a prophet
And they say: the Beneficent hath taken unto Himself a Son. Assuredly ye utter a disastrous thing, whereby almost the heavens are torn, and the earth is split asunder and the mountains fall to ruins, that ye ascribe to the Beneficent a son, when it is not meet for (the Majesty of) the Beneficent that He should chose a son. There is none in the heavens and the earth but cometh unto the Beneficent as a slave. (Qur'an 19:88-93).
