6:4Not one of their Lord’s signs comes to them, but they turn away from it.

6:25Among them are those who listen to you; but We place covers over their hearts, to prevent them from understanding it, and heaviness in their ears. Even if they see every sign, they will not believe in it. Until, when they come to you, to argue with you, those who disbelieve will say, “These are nothing but myths of the ancients.”

6:35If you find their rejection hard to bear, then if you can, seek a tunnel into the earth, or a stairway into the heaven, and bring them a sign. Had God willed, He could have gathered them to guidance. So do not be of the ignorant.

6:37And they say, “If only a sign could come down to him from his Lord.” Say, “God is Able to send down a sign, but most of them do not know.”

6:99And it is He who sends down water from the sky. With it We produce vegetation of all kinds, from which We bring greenery, from which We produce grains in clusters. And palm-trees with hanging clusters, and vineyards, and olives, and pomegranates—similar and dissimilar. Watch their fruits as they grow and ripen. Surely in this are signs for people who believe.

6:112Likewise, We have assigned for every prophet an enemy—human and jinn devils—inspiring one another with fancy words in order to deceive. But had your Lord willed, they would not have done it. So leave them to their fabrications.

6:124When a sign comes to them, they say, “We will not believe unless we are given the like of what was given to God’s messengers.” God knows best where to place His message. Humiliation from God and severe torment will afflict the criminals for their scheming.

6:128On the Day when He gathers them all together: “O assembly of jinn, you have exploited multitudes of humans.” Their adherents among mankind will say, “Our Lord, we have profited from one another, but we have reached the term that you have assigned for us.” He will say, “The Fire is your dwelling, wherein you will remain, except as God wills. Your Lord is Wise and Informed.

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.”
