Tell them, "We believe in what is revealed to us and to you. Our Lord and your Lord is one. We have submitted ourselves to His will". 46 And thus have We revealed the Book to you. So those whom We have given the Book believe in it, and of these there are those who believe in it, and none deny Our communications except the unbelievers. 47 And thou hast not been reciting any book before it, nor hast thou been writing it with thine right hand, for then might the followers of falsehood have doubted. 48 But the Quran is a revelation that is clear to the hearts of those endowed with knowledge. Only the evil-doers refuse to acknowledge Our revelations. 49 They say, 'Why have signs not been gent down upon him from his Lord?' Say: 'The signs are only with God, and I am only a plain warner. 50 Why - is it not enough for them that We have bestowed this divine writ on thee from on high, to be conveyed [by thee] to them? For, verily, in it is [manifested Our] grace, and a reminder to people who will believe. 51
