Surah Al-Kahf 18:90

His Journey East

Allah tells us that Dhul-Qarnayn then traveled from the west of the earth towards the east. Every time he passed a nation, he subjugated the people and called them to Allah. If they obeyed him, all well and good, otherwise he would humiliate them and take their wealth and possessions. From every nation he took what his armies needed to fight the next nation. When he reached the place where the sun rises, as Allah says,

(he found it rising on a people) meaning a nation,

(for whom We (Allah) had provided no shelter against the sun.) meaning, they had no buildings or trees to cover them and shade them from the heat of the sun. Qatadah said, "It was mentioned to us that they were in a land where nothing grew, so when the sun rose they would go into tunnels until it had passed its zenith, then they would come out to go about their daily lives and earn themselves a living."

(So (it was)! And We knew all about him.) Mujahid and As-Suddi said, "This means that Allah knew everything about him and his army, and nothing was hidden from Him, even though they came from so many different nations and lands. For,

(Truly, nothing is hidden from Allah, in the earth or in the heaven.)3:5"

Ayat menjelaskan bahwa Zulkarnain menempuh jalan ke arah Timur. Setelah ia sampai ke pantai Afrika sebelah barat, lalu ia kembali menuju ke arah timur sehingga sampailah ia ke tempat terbitnya matahari di sekitar negeri Tiongkok di mana ia menjumpai segolongan umat manusia yang hidupnya tidak di bawah bangunan rumah dan tidak ada pula pohon-pohon menaunginya dari panasnya matahari. Mereka langsung mendapat sorotan cahaya matahari karena tidak terlindung oleh atap atau bukit-bukit yang berada di sekitarnya. Mereka pada siang hari berada dalam lubang-lubang di bawah tanah dan baru muncul di atas permukaan bumi setelah matahari terbenam, untuk mencari penghidupannya. Keadaan mereka jauh berbeda sekali dengan penghuni dunia yang lainnya, karena mereka hidupnya masih primitif dan tidak mempunyai bangunan untuk tempat tinggal.
