Surah Yusuf (Joseph), Verse 96

فَلَمَّاۤ اَنْ جَآءَ الْبَشِیْرُ اَلْقٰىهُ عَلٰی وَجْهِهٖ فَارْتَدَّ بَصِیْرًا قَالَ اَلَمْ اَقُلْ لَّكُمْ اِنِّیْۤ اَعْلَمُ مِنَ اللّٰهِ مَا لَا تَعْلَمُوْنَ ۟

Falammaaa an jaaa'albasheeru alqaahu 'alaa wajhihee fartadda baseeran qaala alam aqul lakum inneee a'lamu minal laahi maa laa ta'lamoon

“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?'"”
