Quran 6:104 Al-An'am, ayah 104 of 165

قَدْ جَآءَكُم بَصَآئِرُ مِن رَّبِّكُمْ ۖ فَمَنْ أَبْصَرَ فَلِنَفْسِهِۦ ۖ وَمَنْ عَمِىَ فَعَلَيْهَا ۚ وَمَآ أَنَا۠ عَلَيْكُم بِحَفِيظٍ ۝١٠٤

6:104 Proofs have come unto you from your Lord, so whoso seeth, it is for his own good, and whoso is blind is blind to his own hurt. And I am not a keeper over you.
