Surat At-Tawba (The Repentance) - التوبة

وَيَحْلِفُونَ بِٱللَّهِ إِنَّهُمْ لَمِنكُمْ وَمَا هُم مِّنكُمْ وَلَٰكِنَّهُمْ قَوْمٌ يَفْرَقُونَ ﴿٥٦﴾ لَوْ يَجِدُونَ مَلْجَـًٔا أَوْ مَغَٰرَٰتٍ أَوْ مُدَّخَلًا لَّوَلَّوْا۟ إِلَيْهِ وَهُمْ يَجْمَحُونَ﴿٥٧﴾

And they swear by Allah that they are most surely of you, and they are not of you, but they are a people who are afraid (of you). If they could find a refuge or cave or a place to enter into, they would certainly have turned thereto, running away in all haste.
