Muhammad 47:16

Waminhum man yastamiAAu ilayka hattaitha kharajoo min AAindika qaloo lillatheenaootoo alAAilma matha qala anifan ola-ikaallatheena tabaAAa Allahu AAalaquloobihim wattabaAAoo ahwaahum

And among them, [O Muḥammad], 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 Allāh has sealed over their hearts and who have followed their [own] desires.

Among them there are ones who (pretend to) give ear to you, until when they go out from your presence, they say to those who have been given knowledge, “What did he say just now?” Those are the ones on whose hearts Allah has put a seal, and they have followed their desires.
