Prophet Hud - 11:12
"Perhaps your chest will be constricted and you will abandon some of what has been revealed to you because they say, "Should not a treasure have descended to him, or an angel with him?"You are only a warner; Allah is the Controller of all things."
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.
