وَلاَ تَسُبُّواْ الَّذِينَ يَدْعُونَ مِن دُونِ اللّهِ فَيَسُبُّواْ اللّهَ عَدْوًا بِغَيْرِ عِلْمٍ كَذَلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمْ ثُمَّ إِلَى رَبِّهِم مَّرْجِعُهُمْ فَيُنَبِّئُهُم بِمَا كَانُواْ يَعْمَلُونَ
﴿١٠٨﴾
سورة الأنعام
(6/108) And do not revile those whom they call upon besides Allah, lest exceeding the limits they should revile Allah out of ignorance. Thus have We made fair-seeming to every people their deeds; then to their Lord shall be their return. So He will inform them of what they used to do.
Surah Al-An'am
