Surah Al-Hashr — Ayah 12 (59:12)
لَئِنۡ أُخۡرِجُواْ لَا يَخۡرُجُونَ مَعَهُمۡ وَلَئِن قُوتِلُواْ لَا يَنصُرُونَهُمۡ وَلَئِن نَّصَرُوهُمۡ لَيُوَلُّنَّ ٱلۡأَدۡبَٰرَ ثُمَّ لَا يُنصَرُونَ ١٢
English translation (Saheeh International)
If they are expelled, they will not leave with them, and if they are fought, they will not aid them. And [even] if they should aid them, they will surely turn their backs; then [thereafter] they will not be aided.
Brief commentary
If the Muslims exile the Jews, they will not leave with them, and if they fight them, they will neither support nor help them. Even if they go to help or support them against the Muslims, they will flee from the battlefield, after which the hypocrites will never be helped; rather, Allah will humiliate and shame them.
