An-Nisa' 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

They have "Obedience" on their lips; but when they leave thee, a section of them Meditate all night on things very different from what thou tellest them. But Allah records their nightly (plots): So keep clear of them, and put thy trust in Allah, and enough is Allah as a disposer of affairs.
