Surat Al-'Isrā' - سورة الإسراء

نَّحْنُ أَعْلَمُ بِمَا يَسْتَمِعُونَ بِهِ إِذْ يَسْتَمِعُونَ إِلَيْكَ وَإِذْ هُمْ نَجْوَىٰ إِذْ يَقُولُ الظَّالِمُونَ إِن تَتَّبِعُونَ إِلَّا رَجُلًا مَّسْحُورًا

Muhsin Khan: We know best of what they listen to, when they listen to you. And when they take secret counsel, behold, the Zalimun (polytheists and wrong-doers, etc.) say: "You follow none but a bewitched man."
