If you were to take your bible, and read Daniel 9:24-27 to say a muslim, the words that Daniel spoke in those verses... did the muslim person therefore have a vision?
What are you talking about here? Can you please just speak straightforwardly?
No, of course. Daniel 9:24-27 was not ta vision that Daniel had. It was prophesy about the future.
A "vision" can refer to a literal vision that someone literally sees or it can refer to a spoken prophecy. It's called a "vision" in that case because it is giving insight into a future event.
Here is one example of what I'm talking about, so that you can see that I'm not just making this up:
Isaiah 1:1
The vision of Isaiah the son of Amoz, which he saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah. 2 Hear, O heavens, and give ear, O earth: for the Lord hath spoken, I have nourished and brought up children, and they have rebelled against me.
Isaiah did not have a vision in terms literally seeing something in a dream or anything like that. No, the "vision" of Isaiah here is referring to the insight into the future that the Lord had given to him. So, the vision Gabriel referenced in Daniel 9:23 should be understood similarly. He was telling Daniel to understand the vision/prophecy that he was about to tell him, as recorded in verses 24-27.
Here is another example where a "vision" is not something that was literally seen, but that was spoken.
Jeremiah 23:16 Thus saith the Lord of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain:
they speak a vision of their own heart, and not out of the mouth of the Lord.
And here is another example:
Daniel 10:11 And he said unto me, O Daniel, a man greatly beloved, understand the words that I speak unto thee, and stand upright: for unto thee am I now sent. And when he had spoken this word unto me, I stood trembling. 12 Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words. 13 But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia. 14
Now I am come to make thee understand what shall befall thy people in the latter days: for yet the vision is for many days. 15 And when he had spoken such words unto me, I set my face toward the ground, and I became dumb.
In this case, the vision was not something that Daniel saw that would happen, but was something spoken to him by "a certain man clothed in linen, whose loins were girded with fine gold of Uphaz" (Daniel 10:5) regarding what would happen to his "people in the latter days".
