4:81
وَيَقُولُونَ طَاعَةٌۭ فَإِذَا بَرَزُوا۟ مِنْ عِندِكَ بَيَّتَ طَآئِفَةٌۭ مِّنْهُمْ غَيْرَ ٱلَّذِى تَقُولُ ۖ وَٱللَّهُ يَكْتُبُ مَا يُبَيِّتُونَ ۖ فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى ٱللَّهِ ۚ وَكَفَىٰ بِٱللَّهِ وَكِيلًا ٨١

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.
