Yusuf 12:96

فَلَمَّآ أَن جَآءَ ٱلْبَشِيرُ أَلْقَىٰهُ عَلَىٰ وَجْهِهِۦ فَٱرْتَدَّ بَصِيرًۭا ۖ قَالَ أَلَمْ أَقُل لَّكُمْ إِنِّىٓ أَعْلَمُ مِنَ ٱللَّهِ مَا لَا تَعْلَمُونَ

Then when the bearer of the good news came, He cast (the shirt) over his face, and he forthwith regained clear sight. He said: "Did I not say to you, 'I know from Allah that which ye know not?'"
