Quran 4:81 from Surah An-Nisaa on Divine Marvels.
وَيَقُولُونَ طَاعَةٞ فَإِذَا بَرَزُواْ مِنۡ عِندِكَ بَيَّتَ طَآئِفَةٞ مِّنۡهُمۡ غَيۡرَ ٱلَّذِي تَقُولُۖ وَٱللَّهُ يَكۡتُبُ مَا يُبَيِّتُونَۖ فَأَعۡرِضۡ عَنۡهُمۡ وَتَوَكَّلۡ عَلَى ٱللَّهِۚ وَكَفَىٰ بِٱللَّهِ وَكِيلًا
English translation: And they say (We pledge) obedience Then when they leave from you plan by night a group of them other than that which you say But Allah records what they plan by night So turn (away) from them and put (your) trust in Allah And sufficient is Allah (as) a Trustee
Transliteration: wayaquluna ta'atun fa-idha barazu min indika bayyata taifatun min'hum ghayra alladhi taqulu wal-lahu yaktubu ma yubayyituna fa-a'rid anhum watawakkal ala al-lahi wakafa bil-lahi wakilan
