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

“[for] if those [to whom they have pledged themselves] are indeed driven away, they will not go forth with them; and if war is waged against them, they will not come to their succour; and even if they [try to] succour them, they will most certainly turn their backs [in flight], and in the end will [themselves] find no succour.”

((For) indeed if they) i.e. the Banu Qurayzah (are driven out) from Medina (they) the hypocrites (go not out with them, and indeed if they are attacked) by the Prophet (pbuh) (they help not) against Muhammad (pbuh) (and indeed if they had helped them) against Muhammad (pbuh) (they would have turned and fled) in defeat, (and then they would not have been victorious) they will not escape what will befall them.
