۞ أَلَمْ تَرَ إِلَى ٱلَّذِينَ نَافَقُوا۟ يَقُولُونَ لِإِخْوَٰنِهِمُ ٱلَّذِينَ كَفَرُوا۟ مِنْ أَهْلِ ٱلْكِتَٰبِ لَئِنْ أُخْرِجْتُمْ لَنَخْرُجَنَّ مَعَكُمْ وَلَا نُطِيعُ فِيكُمْ أَحَدًا أَبَدًۭا وَإِن قُوتِلْتُمْ لَنَنصُرَنَّكُمْ وَٱللَّهُ يَشْهَدُ إِنَّهُمْ لَكَٰذِبُونَ
Hast thou not observed those who are hypocrites, (how) they tell their brethren who disbelieve among the People of the Scripture: If ye are driven out, we surely will go out with you, and we will never obey anyone against you, and if ye are attacked we verily will help you. And Allah beareth witness that they verily are liars.
Surah Al-Hashr(59:11)
