أَلَم تَرَ إِلَى الَّذينَ تَوَلَّوا قَومًا غَضِبَ اللَّهُ عَلَيهِم ما هُم مِنكُم وَلا مِنهُم وَيَحلِفونَ عَلَى الكَذِبِ وَهُم يَعلَمونَ

Have you not considered those who make allies of a people with whom Allah has become angry? They are neither of you nor of them, and they swear to untruth while they know [they are lying].
