وَلَا تَسُبُّواْ ٱلَّذِينَ يَدۡعُونَ مِن دُونِ ٱللَّهِ فَيَسُبُّواْ ٱللَّهَ عَدۡوَۢا بِغَيۡرِ عِلۡمٖۗ كَذَٰلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمۡ ثُمَّ إِلَىٰ رَبِّهِم مَّرۡجِعُهُمۡ فَيُنَبِّئُهُم بِمَا كَانُواْ يَعۡمَلُونَ

Wa laa tasubbul lazeena yad'oona min doonil laahi fa yasubbul laaha 'adwam bighairi 'ilm; kazaalika zaiyannaa likulli ummatin 'amalahum summa ilaa Rabbihim marji'uhum fa yunabbi'uhum bimaa kaanoo ya'maloon

Revile not ye those whom they call upon besides Allah, lest they out of spite revile Allah in their ignorance. Thus have We made alluring to each people its own doings. In the end will they return to their Lord, and We shall then tell them the truth of all that they did.
