﴿ إِنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَٰبَ لِلنَّاسِ بِٱلْحَقِّ ۖ فَمَنِ ٱهْتَدَىٰ فَلِنَفْسِهِۦ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ ﴾

“BEHOLD, from on high have We bestowed upon thee this divine writ, setting forth the truth for [the benefit of all] mankind. And whoever chooses to be guided [thereby], does so for his own good, and whoever chooses to go astray, goes but astray to his own hurt; and thou hast not the power to determine their fate.”
