In the name of Allah the All Merciful, the Most Merciful, and peace be upon the messengers, and praise be to Allah Lord of the worlds..

My honorable brother, your question is: What is the intended; the barrier of Dhul Qarnain has a large opening at the top and not sealed? Surely this matter refer it to your mind; if the barrier was not cutting off between the two sides of the land of the two easts it would have been easy for gog and magog the penetration from its right or from its left, but it is a great barrier cuts the tunnelly land from the shell-curvature to (the opposite) shell-curvature, but it is not sealed from the top surely it has a great opening, but it is flat, smooth, and high so gog and magog can not scale it to break in from the opening at the top of the barrier, as well they could not make a hole; so they penetrate it to make an opening in its width in order they enter from it, and they had tried but they could not (succeed) since a long time ago and they gave up, and Allah the Most High said: {So they were not able to scale it, nor could they peck a hole in it.} Truthful Allah the Great [Al-Kahf] 18:97

As for the scaling surely it is the climbing on its wall to reach to the high opening at the top of the barrier and it is great as the width of the land of the two easts, as for the pecking a hole so it is the penetration, so they could not because of the mixed solid metallic substance from their side and they do not have other way but to scale it to the top of it to force their way in from above or drill it, surely they could not climb it nor they could poke a hole into it, and the promise of my lord just approached and He shall make it crumble, and the promise of my Lord is ever true. So they surge from behind the barrier then all surge into this world of yours to seduce you from the Truth and we had explained the Truth in details for you may get certain with the True explanatory-statement for the Reminder, but unfortunately your scholars want an Awaited Mahdi following their desires so he does not disobey a command of theirs so they presume that they have a favor upon him that they are the ones who chose him, so it should not be for him to disobey a command for them or violate them in a thing, and if the Truth follows their desires, the earth would perish more and more, and the Awaited Mahdi could not purify the earth from the corruption a (thorough) purification. And it was not for the Truth to follow your desires even if Allah lengthens the era of dialogue for the Awaited Mahdi the lifetime of the call of Noah a thousand years save fifty years (still) the Awaited Mahdi Nasser Mohammad Al-Yemeni would not follow your desires, nor searched for their pleasure and Allah did not make His khalifa in need of them, and Allah shall make him appear over who violated him in a night while they are humbled with humiliation.

And peace be upon the messengers, and praise be to Allah Lord of the worlds..
Your brother the Imam Mahdi Nasser Mohammad Al-Yemeni.
