قَالَ يَٰقَوْمِ أَرَءَيْتُمْ إِن كُنتُ عَلَىٰ بَيِّنَةٍۢ مِّن رَّبِّى وَءَاتَىٰنِى رَحْمَةًۭ مِّنْ عِندِهِۦ فَعُمِّيَتْ عَلَيْكُمْ أَنُلْزِمُكُمُوهَا وَأَنتُمْ لَهَا كَٰرِهُونَ
He said: O my people! Bethink you, if I rely on a clear proof from my Lord and there hath come unto me a mercy from His presence, and it hath been made obscure to you, can we compel you to accept it when ye are averse thereto?
