Dhul-Qarnain: His identity, period and country and the reason why he was so named
The wall of Zulqarnain By Shaykh Ahmed Ali
Many different opinions have been expressed as to the location of the iron wall of Zulqarnain. Having read many books, the best on the subject I came across was Sheikh Hifzur-Rahman's "Stories of the Qur'an" and thus have chosen to share a brief summary of what he has written.
He writes "The Yajuj Ma'juj caused destruction and blood- shed in a vast area, and because of their oppression many barriers and walls were erected in different times and places by different kings. Four being the most famous:
1) The Great Wall of China which was built by the Chinese King Fagfor 3460 years after Prophet Adam was put on the Earth.
2) The wall in central Asia near Bukhara and Tirmidh in a place called Derbent.
3) The wall in Dagistan Russia also known as Derbent near the Caspian sea.
4) The wall which is in the westerly direction to the third in the region of the Caucasus.
Because these walls were built for one purpose and are all situated in the North, it has always been very difficult to determine exactly the wall built by Zulqarnain."
He further writes, "The biggest out of the four is the great wall of China and nobody is of the opinion that this is the wall built by Zulqarnain as it is in the easterly direction while the Qur'an indicates the wall of Zulqarnain is in the Northerly direction."
Thus leaving walls 2, 3, and 4.
He writes, "Historians like Masoodi, Istakhari and Hamawi are of the opinion that the wall of Zulqamain is wall number 3 or 4. Those that have said it is wall number two have confused the issue due to the location of Derbent which is near Bukhara and also in Degistan.''
He finally writes, ''Out of two, the historians are of the opinion that it is wall 3 or 4, the master of hadith Allama Anwar Shah Kashmiri in his book Aqeeda-tul-Islam holds the opinion that the wall of Zulqarnain is wall number 4, the one in the region of Caucasus.' (Stories of the Qu'ran)
After this short summary I find myself inclined to Allama Aloosi's opinion I conclude with his words, ''We do not know the location of this wall and it is very probable that great seas and mountains stand between us and the wall, and between Ya'juj Ma'juj and the rest of the world.''
