And when We said to you: Surely your Lord encompasses men; and We did not make the vision which We showed you but a trial for men and the cursed tree in the Quran as well; and We cause them to fear, but it only adds to their great inordinacy.

Certainly Allah had shown to His Messenger the vision with truth: you shall most certainly enter the Sacred Mosque, if Allah pleases, in security, (some) having their heads shaved and (others) having their hair cut, you shall not fear, but He knows what you do not know, so He brought about a near victory before that.
