قُلْ أَتُحَآجُّونَنَا فِى ٱللَّهِ وَهُوَ رَبُّنَا وَرَبُّكُمْ وَلَنَآ أَعْمَـٰلُنَا وَلَكُمْ أَعْمَـٰلُكُمْ وَنَحْنُ لَهُۥ مُخْلِصُونَ١٣٩Say (unto the People of the Scripture): Dispute ye with us concerning Allah when He is our Lord and your Lord? Ours are our works and yours your works. We look to Him alone.
