And We have set a bar before them and a bar behind them, and (thus) have covered them so that they see not. Whether thou warn them or thou warn them not, it is alike for them, for they believe not. 36:9
Go with this shirt of mine and lay it on my father's face, he will become (again) a seer....
When the caravan departed their father had said: Truly I am conscious of the breath of Joseph, though ye call me dotard.
... He laid it on his face and he became a seer once more. 12:93
