6:8And they say, “Why was an angel not sent down to him.” Had We sent down an angel, the matter would have been settled, and they would not have been reprieved.

6:58Say, “If I possessed what you seek me to hasten, the matter between you and me would have been settled. God is well aware of the unjust.”

6:115The Word of your Lord has been completed, in truth and justice. There is no changing to His words. He is the Hearer, the Knower.

6:157Or lest you say, “Had the Scripture been revealed to us, we would have been better guided than they.” Clarification has come to you from your Lord, and guidance, and mercy. Who then does greater wrong than he who gives the lie to God's messages, and turns away from them? We will repay those who turn away from Our messages with the worst kind of punishment, because of their turning away.
