Surah Al-Anbiya, ayah 36

21:36

وَإِذَا رَءَاكَ ٱلَّذِينَ كَفَرُوٓاْ إِن يَتَّخِذُونَكَ إِلَّا هُزُوًا أَهَٰذَا ٱلَّذِي يَذۡكُرُ ءَالِهَتَكُمۡ وَهُم بِذِكۡرِ ٱلرَّحۡمَٰنِ هُمۡ كَٰفِرُونَ ٣٦

Wa idhā ra'ākal-ladhīna kafarū in yattakhidhūnaka illā huzuwan ahādhal-ladhī yadhkuru ālihatakum wahum bidhikrir-rahmāni hum kāfirūn

And when those who disbelieve see you, [O Muḥammad], they take you not except in ridicule, [saying], "Is this the one who mentions [i.e., insults] your gods?" And they are, at the mention of the Most Merciful, disbelievers.
