وَمِنْهُم مَّن يَسْتَمِعُ إِلَيْكَ حَتَّى إِذَا خَرَجُوا مِنْ عِندِكَ قَالُوا لِلَّذِينَ أُوتُوا الْعِلْمَ مَاذَا قَالَ آنِفاً أُوْلَئِكَ الَّذِينَ طَبَعَ اللَّهُ عَلَى قُلُوبِهِمْ وَاتَّبَعُوا أَهْوَاءهُمْ

16. Among them (the people of Madīnah) are some who give ear to you, but when they go out from your presence, they ask (with arrogance and derision) those who have been given (some) knowledge (of the truths of the Religion): "What has he said just now?" Those are they whose hearts God has sealed, and who follow their lusts and fancies.
