In the Quran the Earth is flat and the Sun Sets in a Murky Water

In the Quran the Earth is flat and the Sun Sets in a Murky Water 
The well Known common belief in Islam is the earth is flat and the mountains are to fix it and stabilize it in place. The heaven is flat to cover the earth and God stops it from falling on earth. The heaven is 7 layers (7 heavens) which the prophet Muhamed traveled through in the(Israa and Maarage). The earth is also 7 layers (7 earths) which the Devils live in. Some Islamic Schoolers today still argue the sphericity and the rotation of the earth. I have watched a schooler on video claiming if the earth rotates under an airplane, it should land in the same place it took off from.

Chapter 18 The cave سورة الكهف - Al-Kahf: Verse 86

حَتَّىٰ إِذَا بَلَغَ مَغْرِبَ الشَّمْسِ وَجَدَهَا تَغْرُبُ فِي عَيْنٍ حَمِئَةٍ وَوَجَدَ عِنْدَهَا قَوْمًا ۗ قُلْنَا يَا ذَا الْقَرْنَيْنِ إِمَّا أَنْ تُعَذِّبَ وَإِمَّا أَنْ تَتَّخِذَ فِيهِمْ حُسْنًا

Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness."

Arabic: والارض بعد ذلك دحاها

Transliteration: Waal-arda baAAda thalika dahaha

Literal: And the earth/Planet Earth after that He stretched/spread it. ^[13]
