Surah An-Nur, Verse 47

وَيَقُولُونَ ءَامَنَّا بِٱللَّهِ وَبِٱلرَّسُولِ وَأَطَعۡنَا ثُمَّ يَتَوَلَّىٰ فَرِيقٞ مِّنۡهُم مِّنۢ بَعۡدِ ذَٰلِكَۚ وَمَآ أُوْلَٰٓئِكَ بِٱلۡمُؤۡمِنِينَ٤٧

wayaqūlūna āmannā bil-lahi wabil-rasūli wa-aṭaʿnā thumma yatawallā farīqun min'hum min baʿdi dhālika wamā ulāika bil-mu'minīna

But they [i.e., the hypocrites] say, "We have believed in Allāh and in the Messenger, and we obey"; then a party of them turns away after that. And those are not believers.
