I would think the binding would have more to do with false apostles, bringing false prophecy. Which it was possible to deceive the elect while we had prophecy in part.
When God finished bringing any more new prophecy he sealed up His now perfect or complete will and added a warning to any who would add or subtract from the whole. In that if any man say I received new prophecy from the Lord we are to believe not. It is how we try the spirits according to 1 John to see if they are of the things of God or of men.
Any new prophecy to include that of Mohamed and his false prophecy, the Koran would show him as well as any other to be a false apostles, false Christ’s, as antichrists .
And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not: For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, “if it were possible”, even the elect.But take ye heed: behold, I have foretold you all things.But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light, Mar 13:21
That tribulation will last right up till the last day , the second resurrection. Until then Satan will deceive the nations of people who know not God with the working of Satan with all power and signs and lying wonders,
The binding only affects those who will not go above that which is written seeing we have the perfect..with no other prophecy to be expected.
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part.But when that which is perfect is come, then that which is in part shall be done away.When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. 1Co 13:9
