Surah Muhammad (Muhammad), Verse 16

وَمِنْهُمْ مَّنْ یَّسْتَمِعُ اِلَیْكَ حَتّٰۤی اِذَا خَرَجُوْا مِنْ عِنْدِكَ قَالُوْا لِلَّذِیْنَ اُوْتُوا الْعِلْمَ مَاذَا قَالَ اٰنِفًا اُولٰٓىِٕكَ الَّذِیْنَ طَبَعَ اللّٰهُ عَلٰی قُلُوْبِهِمْ وَاتَّبَعُوْۤا اَهْوَآءَهُمْ ۟

“And among them are men who listen to thee, but in the end, when they go out from thee, they say to those who have received Knowledge, "What is it he said just then?" Such are men whose hearts Allah has sealed, and who follow their own lusts.”
