وَمِنْهُم مَّن يَسْتَمِعُ إِلَيْكَ حَتَّىٰ إِذَا خَرَجُوا مِنْ عِندِكَ قَالُوا لِلَّذِينَ أُوتُوا الْعِلْمَ مَاذَا قَالَ آنِفًا ۚ أُولَٰئِكَ الَّذِينَ طَبَعَ اللَّهُ عَلَىٰ قُلُوبِهِمْ وَاتَّبَعُوا أَهْوَاءَهُمْ (16)
(47:16) Among them some give ear to you. But no sooner do they leave your presence than they ask those endowed with knowledge: 'What is it that he said just now?' *25 Such are those whose hearts Allah has sealed and who pursue their lusts. *26
*25) This is concerning those disbelievers and hypocrites and unbelieving followers of the former Books, who sat in the assemblies of the Holy Prophet, listened to his discourses, or the verses of the Qur'an, but since in their hearts they were averse to the themes presented by him, they would understand nothing in spite of listening to him. Therefore, when they came out, they would ask the Muslims, "What was he saying just now?"
*26) This was the real cause because of which their inner ears had become deaf tothe teachings of the Holy Prophet; they were the slaves of their lusts, and the teachings that the Holy Prophet was presenting fell against their lusts. Therefore ,if ever they sat in the assemblies of the Holy Prophet and listened to him, they would understand nothing.
