Al-Fath 48:20

WaAAadakumu Allahu maghanimakatheeratan ta/khuthoonaha faAAajjala lakum hathihiwakaffa aydiya annasi AAankum walitakoona ayatanlilmu/mineena wayahdiyakum siratan mustaqeema

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.

Allah had promised you many spoils that you would receive, so He gave these to you sooner, and stopped the hands of the people from (harming) you. And (He did this) so that it becomes a sign for believers, and so that He guides you to the right path.
