Quran 59:12 Al-Hashr, ayah 12 of 24

لَئِنْ أُخْرِجُوا۟ لَا يَخْرُجُونَ مَعَهُمْ وَلَئِن قُوتِلُوا۟ لَا يَنصُرُونَهُمْ وَلَئِن نَّصَرُوهُمْ لَيُوَلُّنَّ ٱلْأَدْبَـٰرَ ثُمَّ لَا يُنصَرُونَ ۝١٢

59:12 (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.
