﴿ وَمِنْهُم مَّن يَسْتَمِعُ إِلَيْكَ حَتَّىٰٓ إِذَا خَرَجُوا۟ مِنْ عِندِكَ قَالُوا۟ لِلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ مَاذَا قَالَ ءَانِفًا ۚ أُو۟لَٰٓئِكَ ٱلَّذِينَ طَبَعَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَٱتَّبَعُوٓا۟ أَهْوَآءَهُمْ ﴾

“Now among those [hapless sinners] are such as [pretend to] listen to thee, [O Muhammad,] and then, as soon as they leave thy presence, speak [with scorn] unto those who have understood [thy mes­sage]: “What is it that he has said just now?” It is such as these whose hearts God has sealed because they [always] followed but their own lusts”

And there are some among them namely the disbelievers who listen to you during the Friday sermon — and these are the hypocrites; until when they go forth from you they say to those who have been given knowledge that is to say to the knowledgeable ones among the Companions of the Prophet such as ‘Abd Allāh Ibn Mas‘ūd and ‘Abd Allāh Ibn ‘Abbās in derision and mockery ‘What was he saying just now?’ read ānifan or anifan meaning al-sā‘a ‘just now’. In other words they mean to say ‘we will not go back to listen to him again’. Those are the ones on whose hearts God has set a seal of disbelief and who follow their own desires in acting with hypocrisy.
