(meaning the believing ones in Makkah) Whom, without knowing, you might have trodden down, and thus something hateful might have afflicted you on their account without (your) knowledge . Hence, the reason for the Treaty of Hudaybiyya , was to protect the believers who were in Makkah, as otherwise they would have been killed (by the non-believers of Makkah).

As a result, when the reconciliation took place, they were safe, and Al-Islam was triumphant, and it was said, ‘That reconciliation was the greatest victory for the Muslims over the ones, they overcame’.

So Allah -azwj Informed His -azwj Prophet -saww of the reason for the reconciliation, which was for the safety of the Believing men and the Believing women who were at Makkah, and had it not been for the reconciliation and a battle had ensued, they would have been killed . فلما كان الصلح آمنوا و أظهروا الإسلام، و يقال: إن ذلك الصلح كان أعظم فتحا على المسلمين من غلبهم.

So when the reconciliation took place, they were safe, and Al-Islam was triumphant, and it was said, ‘That reconciliation was the greatest victory for the Muslims over the ones they overcame’.
