Surah Al-Isra' (The Night Journey), Verse 47

نَحْنُ اَعْلَمُ بِمَا یَسْتَمِعُوْنَ بِهٖۤ اِذْ یَسْتَمِعُوْنَ اِلَیْكَ وَاِذْ هُمْ نَجْوٰۤی اِذْ یَقُوْلُ الظّٰلِمُوْنَ اِنْ تَتَّبِعُوْنَ اِلَّا رَجُلًا مَّسْحُوْرًا ۟

Nahnu a'lamu bimaa yastami'oona biheee iz yastami'oona ilaika wa iz hum najwaaa iz yaqooluz zaalimoona in tattabi'oona illaa rajulam mas hooraa

“We know best why it is they listen, when they listen to thee; and when they meet in private conference, behold, the wicked say, "Ye follow none other than a man bewitched!"”
