6:59With Him are the keys of the unseen; none knows them except He. And He knows everything on land and in the sea. Not a leaf falls but He knows it; and there is not a single grain in the darkness of earth, nor is there anything wet or dry, but is in a clear record.

6:91They do not value God as He should be valued, when they say, “God did not reveal anything to any human being.” Say, “Who revealed the Scripture which Moses brought—a light and guidance for humanity?” You put it on scrolls, displaying them, yet concealing much. And you were taught what you did not know—neither you, nor your ancestors. Say, “God;” then leave them toying away in their speculation.

6:148The polytheists will say, “Had God willed, we would not have practiced idolatry, nor would have our forefathers, nor would we have prohibited anything.” Likewise those before them lied, until they tasted Our might. Say, “Do you have any knowledge that you can produce for us? You follow nothing but conjecture, and you only guess.”

6:158Are they waiting for anything but for the angels to come to them, or for your Lord to arrive, or for some of your Lord’s signs to come? On the Day when some of your Lord’s signs come, no soul will benefit from its faith unless it had believed previously, or had earned goodness through its faith. Say, “Wait, we too are waiting.”
