Surah Al-Hashr Verse 12 - English Translation by Ali Unal
Surah Al-Hashrلَئِنۡ أُخۡرِجُواْ لَا يَخۡرُجُونَ مَعَهُمۡ وَلَئِن قُوتِلُواْ لَا يَنصُرُونَهُمۡ وَلَئِن نَّصَرُوهُمۡ لَيُوَلُّنَّ ٱلۡأَدۡبَٰرَ ثُمَّ لَا يُنصَرُونَ
For if they are indeed driven away, they will never go out with them, and if war is waged against them, they will never help them. Even supposing they would help them (in such an eventuality), they would most certainly turn their backs in flight, and so they would not receive help (from anywhere, and be destroyed because of their manifest treachery to the Muslims)
