Dhul-Qarnayn could possible be the land of Zhao, Qin, Yan now China1. Quran citation 18:90 there is a reference of Dhul-Qarnayn following a course until the land where the sun rises. Zhao, Qin, Yan can be found at where the east side of China is now, thus where the sun rises. Dhul-Qarnayn build wall might be the foundation of the wall that defended China from Mongolia. Estimation date might be from 1200 b.c to 500 b.c, as Zhao, Qin, Yan, Wei, Qi started building defense walls at around 800 to 500 b.c. Zhao Qin Yan
2. Referencing to Dhul-Kifl who might be Buddha, Kifl referring to Kapil(avastu) as Palestine for Filistine is in arabic. Kapilavastu was the place Buddha was supposed to be born or was born near. Birth place of Buddha.
The above 2 reasons might justify that Dhul-Qharnayn was indeed one that went to the east of Chinawhere the sun rises and also the one who gave China the idea of building the great Chinese wall.
Quran citation 18:90
"Till, when he(Dhul-Qarnayn) reached the rising-place of the sun, he found it rising on a people for whom We(Allah) had appointed no shelter therefrom."
