﴿ وَيَحْلِفُونَ بِٱللَّهِ إِنَّهُمْ لَمِنكُمْ وَمَا هُم مِّنكُمْ وَلَٰكِنَّهُمْ قَوْمٌۭ يَفْرَقُونَ ﴾

“And they swear by God that they do indeed belong to you -the while they do not belong to you, but are [only] people ridden by fear:”

(And they) 'Abdullah Ibn Ubayy and his host (swear by Allah that they are in truth of you) with you secretly and openly, (when they are not of you) with you, (but they are folk who are afraid) of your swords.
