قُلْ مَن ذَا ٱلَّذِى يَعْصِمُكُم مِّنَ ٱللَّهِ إِنْ أَرَادَ بِكُمْ سُوٓءًا أَوْ أَرَادَ بِكُمْ رَحْمَةًۭ ۚ وَلَا يَجِدُونَ لَهُم مِّن دُونِ ٱللَّهِ وَلِيًّۭا وَلَا نَصِيرًۭا
Say: Who is he who can preserve you from Allah if He intendeth harm for you, or intendeth mercy for you. They will not find that they have any friend or helper other than Allah.
