Sura al-Anʿām 6:108

وَلَا تَسُبُّوا۟ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّـهِ فَيَسُبُّوا۟ ٱللَّـهَ عَدْوًۢا بِغَيْرِ عِلْمٍ كَذَٰلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمْ ثُمَّ إِلَىٰ رَبِّهِم مَّرْجِعُهُمْ فَيُنَبِّئُهُم بِمَا كَانُوا۟ يَعْمَلُونَ

wa-lā tasubbū lladhīna yadʿūna min dūni allāhi fa-yasubbū allāha ʿadwan bi-ghayri ʿilmin ka-dhālika zayyannā li-kulli ummatin ʿamalahum thumma ilā rabbihim marjiʿuhum fa-yunabbiʾuhum bi-mā kānū yaʿmalūna

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.
