And those who have no knowledge say: Why does not Allah speak to us or a sign come to us? Even thus said those before them, the like of what they say; their hearts are all alike. Indeed We have made the communications clear for a people who are sure.

He said: My Lord! appoint a sign for me. Said He: Your sign is that you should not speak to men for three days except by signs; and remember your Lord much and glorify Him in the evening and the morning.

He said: My Lord! give me a sign. He said: Your sign is that you will not be able to speak to the people three nights while in sound health.

And when the word shall come to pass against them, We shall bring forth for them a creature from the earth that shall i wound them, because people did not believe in Our communications.

And those who disbelieve shall be driven to hell in companies; until, when they come to it, its doors shall be opened, and the keepers of it shall say to them: Did not there come to you messengers from among you reciting to you the communications of your Lord and warning you of the meeting of this day of yours? They shall say: Yea! But the sentence of punishment was due against the unbelievers.
