The Forgiver - 40:78 We have told you of some of the messengers We sent before you, and of some We have not told you. No messenger can bring a miracle except by the permission of Allah. When Allah´s command comes, judgment will be given according to the truth, and those who advocate falsehood will be losers therein.
What was the miracle given to Prophet Muhammad?
The Spider/29:50 "They said, "Should not a miracle have descended to him from your Lord?"Say, "Miracles are with Allah. I am only a clear warner."
The Spider/29:51 Is it not enough for them that We have sent down this Book to you and it has been read to them? In that is a mercy and an admonition for a people who believe.
