يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ عَلَيۡكُمۡ أَنفُسَكُمۡۖ لَا يَضُرُّكُم مَّن ضَلَّ إِذَا ٱهۡتَدَيۡتُمۡۚ إِلَى ٱللَّهِ مَرۡجِعُكُمۡ جَمِيعٗا فَيُنَبِّئُكُم بِمَا كُنتُمۡ تَعۡمَلُونَ ١٠٥
O you who have believed, upon you is [responsibility for] yourselves. Those who have gone astray will not harm you when you have been guided. To Allāh is your return all together; then He will inform you of what you used to do.
Translation: Saheeh International (English)
Each word's meaning and sound
O you who faith in Allah, follow His Messenger and practise His laws, you are only responsible for your own souls, so only do that which benefits them. Those people who are misguided, and who do not respond to you, will not harm you if you are on the right path. Being on the right path includes encouraging good and forbidding evil. On the Day of Rising, all of you will return to Allah only and He will tell you about what you used to do in the world and repay your actions.
