إِنَّآ أَنزَلۡنَا عَلَيۡكَ ٱلۡكِتَٰبَ لِلنَّاسِ بِٱلۡحَقِّۖ فَمَنِ ٱهۡتَدَىٰ فَلِنَفۡسِهِۦۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيۡهَاۖ وَمَآ أَنتَ عَلَيۡهِم بِوَكِيلٍ ٤١
Indeed, We sent down to you the Book for the people in truth. So whoever is guided - it is for [the benefit of] his soul; and whoever goes astray only goes astray to its detriment. And you are not a manager [i.e., authority] over them.
Translation: Saheeh International (English)
Each word's meaning and sound
I sent down to you, O Messenger, the Qur’ān for people with the truth for you to warn them. Whoever follows guidance then the benefit of his guidance is only for his own self. Allah does not benefit from his guidance as He is in no need of it. Whoever strays then the harm of his straying is to his own detriment. Allah is not harmed by his straying. You are not in charge of them so as to force guidance on them. Your duty is only to convey to them what you have been instructed to convey.
