﴿ وَأَوْرَثَكُمْ أَرْضَهُمْ وَدِيَٰرَهُمْ وَأَمْوَٰلَهُمْ وَأَرْضًۭا لَّمْ تَطَـُٔوهَا ۚ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرًۭا ﴾

“and He made you heirs to their lands, and their houses, and their goods - and [promised you] lands on which you had never yet set foot: for God has indeed the power to will anything.”

At the Battle of Ahzab, or the Trenches, conditions were very severe. But, in this battle the stage of regular fighting was never reached. Almighty God sent stormy winds and an army of angels against the enemies and terrified them to such an extent that they themselves fled the battlefield. The Jews of Madinah (the Banu Qurayzah) had entered into a pact of peace with the Muslims, but on the occasion of the Battle of Ahzab, they betrayed the Muslims. In breach of the pact, they supported the idolaters. Therefore, when the army of the attackers left Madinah, the Prophet Muhammad, as ordained by God, invaded the areas occupied by the Banu Qurayzah and the Islamic forces besieged their forts. The siege lasted for twenty five days. When they surrendered, everything that they possessed was forfeited.
