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.
And insult not those whom they (disbelievers) worship besides Allah, lest they insult Allah wrongfully without knowledge. Thus We have made fair-seeming to each people its own doings; then to their Lord is their return and He shall then inform them of all that they used to do.
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.
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.
(Surah al-An'aam Surah 6, ayah 108)
