And He let you inherit their land and their homes and their wealth, and a land you have not trodden (so far). And Allah is Powerful to do anything. (9)
(9). These two verses refer to Banu qurayzah, the Jewish tribe who had entered into a treaty with the Muslims not to fight against them, and not to support the enemies of the Muslims. But at the time of the battle of Ahzab, they violated the terms of the treaty and supported the coalition forces. Even earlier, they had been constantly conspiring against the Muslims to an intolerable extent. After the battle of Ahzab was over, the Holy Prophet ﷺ besieged the fortress of Banu qurayzah, and finally, they had to surrender, and most of their men were killed, and the women and children were made captives. This event has been referred to in these verses. At the same time, Allah Ta’ ala has given a good news to the Muslims that they would conquer some other lands which they had not entered before. The words, "and a land you have not trodden" refer to such future victories, especially to the conquest of Khyber that followed within a few years after the battle of Ahzab.
