Overall meaning :
Almighty Allah says: Allah drove back the unbelieving Confederates to their lands utterly empty-handed, seething with rage due to the fierce wind that struck them and for not having secured victory. They did not achieve any good at all, and Allah spared the faithful the need to fight and repelled the unbelievers. Allah is All-Mighty, All-Powerful.
Allah brought down the treacherous Banu Quraydhah Jews, who supported the Confederates in the war against Allah’s Messenger and the Muslims, from their strongholds and cast terror into their hearts, so that some of them you, Muslims, killed and some you took captive. And He gave you their lands, their houses and their wealth, and yet another land on which you have not set foot before. Truly, Allah has power over all things.
