Al-An'am 6:108

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 108

And do not insult those they invoke other than Allah, lest they insult Allah in enmity without knowledge. Thus We have made pleasing to every community their deeds. Then to their Lord is their return, and He will inform them about what they used to do
