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.

Those who are left behind will say when you set forth for the gaining of acquisitions: Allow us (that) we may follow you. They desire to change the world of Allah. Say: By no means shall you follow us; thus did Allah say before. But they will say: Nay! you are jealous of us. Nay! they do not understand but a little.
