وَيَحْلِفُونَ بِٱللَّهِ إِنَّهُمْ لَمِنكُمْ وَمَا هُم مِّنكُمْ وَلَـٰكِنَّهُمْ قَوْمٌ يَفْرَقُونَ

Wayahlifoona billahiinnahum laminkum wama hum minkum walakinnahumqawmun yafraqoon

And they swear by Allāh that they are from among you while they are not from among you; but they are a people who are afraid.
