And they swear by Allah that they are from among you while they are not from among you; but they are a people who are afraid.
The Saheeh International Quran Translation
وَيَحْلِفُونَ بِٱللَّهِ إِنَّهُمْ لَمِنكُمْ وَمَا هُم مِّنكُمْ وَلَٰكِنَّهُمْ قَوْمٌ يَفْرَقُونَAnd they swear by Allah that they are from among you while they are not from among you; but they are a people who are afraid.
