Surah Al-Baqarah, Verse 14

وَإِذَا لَقُواْ ٱلَّذِينَ ءَامَنُواْ قَالُوٓاْ ءَامَنَّا وَإِذَا خَلَوۡاْ إِلَىٰ شَيَٰطِينِهِمۡ قَالُوٓاْ إِنَّا مَعَكُمۡ إِنَّمَا نَحۡنُ مُسۡتَهۡزِءُونَ ﴿١٤﴾

Ve iza lekullezıne amenu kalu amenna* ve iza halev ila şeyatıynihim kalu inna meaküm innema nahnü müstehziun

“When they meet those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting”
