Is the location of the barrier built by Dhul-Qarnayn known?

The questioner:
May Allah reward you, Honorable Shaykh. This questioner asks: Is the location of the barrier built by Dhul-Qarnayn known?

The Shaykh:
By Allah, I do not know it. If any of you knows it, I do not know it. But we believe in it and that it exists, as Allah (Glorified and Exalted is He) mentioned. Not everything that exists do we know and see; perhaps Allah (Mighty and Majestic) conceals it until a time, then it appears at its appointed time. Yes.

The presenter:
May Allah reward you, Honorable Shaykh.

The Shaykh:
Who says there is no barrier because airplanes and the world have been discovered and there is no barrier? If there were a barrier, this would be ignorance, and I seek refuge in Allah. There are things that Allah (Mighty and Majestic) conceals from people. People have not encompassed the entire earth; there are things in it they do not know about, things they cannot reach, and things they are unable to access. Indeed, airplanes crash if they try to go there. Allah is vast and His dominion is vast (Glorified and Exalted is He). It is not a condition of an existing thing that you see it, observe it, or find it. This is not found. Allah conceals it until a time, then it appears.
Look, for example, at oil. The previous nations did not find it. And you found it and enjoyed its benefits, because its time had not come. So there are things that do not appear except at their appointed times. . Yes.
