Allāh has promised you much booty that you will take [in the future] and has hastened for you this [victory] and withheld the hands of people from you - that it may be a sign for the believers and [that] He may guide you to a straight path.
O believers! Allah promises you of acquiring many spoils in future Islamic victories, but He has given you the spoils of Khaybar in advance and stopped the hands of the Jews when they intended to capture your families after you. And He has done this so that these advanced spoils become a sign for you of the help of Allah and His support for you. And Allah guides you to a straight path in which there is no deviance.
