لَئِنْ أُخْرِجُوا۟ لَا يَخْرُجُونَ مَعَهُمْ وَلَئِن قُوتِلُوا۟ لَا يَنصُرُونَهُمْ وَلَئِن نَّصَرُوهُمْ لَيُوَلُّنَّ ٱلْأَدْبَٰرَ ثُمَّ لَا يُنصَرُونَ
(For) indeed if they are driven out they go not out with them, and indeed if they are attacked they help them not, and indeed if they had helped them they would have turned and fled, and then they would not have been victorious.
Surah Al-Hashr(59:12)
