The earth is flat because the Quran says so using all the words in the Arabic vocabulary which can possibly mean flat. Let us review the following words used by the Quran to describe the flatness of the earth%u2019s surface:
1. Sutehat: If you want to describe something as flat in Arabic then there is no better way than using this word. Sateh means flat, sutehat means flattened out. Q. 88:20 Nor even how the earth has been (sutehat) flattened out?
2. Bisata: also means flat. The Arabic word bisata means a flat sheet or a carpet. Q. 71: 19 And God has laid the earth for you as a (bisata) carpet
3. Madda: means stretched out until the object becomes flat, like what happens when you take a ball of dough and stretch it until it becomes flat.
