Al-Hashr 59:12

لَئِنْ أُخْرِجُوا۟ لَا يَخْرُجُونَ مَعَهُمْ وَلَئِن قُوتِلُوا۟ لَا يَنصُرُونَهُمْ وَلَئِن نَّصَرُوهُمْ لَيُوَلُّنَّ ٱلْأَدْبَٰرَ ثُمَّ لَا يُنصَرُونَ

If they are expelled, never will they go out with them; and if they are attacked (in fight), they will never help them; and if they do help them, they will turn their backs; so they will receive no help.
