وَلَا تَسُبُّوا۟ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ فَيَسُبُّوا۟ ٱللَّهَ عَدْوًۢا بِغَيْرِ عِلْمٍۢ ۗ كَذَٰلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمْ ثُمَّ إِلَىٰ رَبِّهِم مَّرْجِعُهُمْ فَيُنَبِّئُهُم بِمَا كَانُوا۟ يَعْمَلُونَ
Revile not those unto whom they pray beside Allah lest they wrongfully revile Allah through ignorance. Thus unto every nation have We made their deed seem fair. Then unto their Lord is their return, and He will tell them what they used to do.
