Surah Al-Hashr, ayah 11

59:11

۞ أَلَمۡ تَرَ إِلَى ٱلَّذِينَ نَافَقُواْ يَقُولُونَ لِإِخۡوَٰنِهِمُ ٱلَّذِينَ كَفَرُواْ مِنۡ أَهۡلِ ٱلۡكِتَٰبِ لَئِنۡ أُخۡرِجۡتُمۡ لَنَخۡرُجَنَّ مَعَكُمۡ وَلَا نُطِيعُ فِيكُمۡ أَحَدًا أَبَدٗا وَإِن قُوتِلۡتُمۡ لَنَنصُرَنَّكُمۡ وَٱللَّهُ يَشۡهَدُ إِنَّهُمۡ لَكَٰذِبُونَ ١١

Alam tara ilal-ladhīna nāfaqū yaqūlūna li ikhwānihimul-ladhīna kafarū min ahlil-kitābi la in ukhrijtum lanakhrujanna ma'akum walā nutī'u fīkum ahadan abadan wa in qūtiltum lanansurannakum wallāhu yashhadu innahum lakādhibūn

Have you not considered those who practice hypocrisy, saying to their brothers [i.e., associates] who have disbelieved among the People of the Scripture, "If you are expelled, we will surely leave with you, and we will not obey, in regard to you, anyone - ever; and if you are fought, we will surely aid you." But Allāh testifies that they are liars.
