Surah Al-Isra, ayah 47

17:47

نَّحۡنُ أَعۡلَمُ بِمَا يَسۡتَمِعُونَ بِهِۦٓ إِذۡ يَسۡتَمِعُونَ إِلَيۡكَ وَإِذۡ هُمۡ نَجۡوَىٰٓ إِذۡ يَقُولُ ٱلظَّٰلِمُونَ إِن تَتَّبِعُونَ إِلَّا رَجُلٗا مَّسۡحُورًا ٤٧

Nnahnu a'lamu bimā yastami'ūna bihī idh yastami'ūna ilayka wa idh hum najwā idh yaqūluz-zālimūna in tattabi'ūna illā rajulam mashūrā

We are most knowing of how they listen to it when they listen to you and [of] when they are in private conversation, when the wrongdoers say, "You follow not but a man affected by magic."
