وَيَقُولُونَ طَاعَةٌۭ فَإِذَا بَرَزُوا۟ مِنْ عِندِكَ بَيَّتَ طَآئِفَةٌۭ مِّنْهُمْ غَيْرَ ٱلَّذِى تَقُولُ ۖ وَٱللَّهُ يَكْتُبُ مَا يُبَيِّتُونَ ۖ فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى ٱللَّهِ ۚ وَكَفَىٰ بِٱللَّهِ وَكِيلًا
And they say, "[We pledge] obedience." But when they leave you, a group of them spend the night determining to do other than what you say. But Allah records what they plan by night. So leave them alone and rely upon Allah. And sufficient is Allah as Disposer of affairs.
