وَمِنهُم مَن يَستَمِعُ إِلَيكَ حَتّىٰ إِذا خَرَجوا مِن عِندِكَ قالوا لِلَّذينَ أوتُوا العِلمَ ماذا قالَ آنِفًا ۚ أُولـٰئِكَ الَّذينَ طَبَعَ اللَّهُ عَلىٰ قُلوبِهِم وَاتَّبَعوا أَهواءَهُم

And among them, [O Muhammad], are those who listen to you, until when they depart from you, they say to those who were given knowledge, "What has he said just now?" Those are the ones of whom Allah has sealed over their hearts and who have followed their [own] desires.
