الآية رقم (6) - وَالْأَرْضِ وَمَا طَحَاهَا

(6) - (And [by] the earth and He who spread it. (6))

The earth is stretched from all sides. Allah (swt) is swears by the earth that He (swt) spread and extended, so as when Allah (swt) says:

  {وَالْأَرْضَ مَدَدْنَاهَا وَأَلْقَيْنَا فِيهَا رَوَاسِيَ وَأَنبَتْنَا فِيهَا مِن كُلِّ زَوْجٍ بَهِيجٍ }

(And the earth – We spread it out and cast therein firmly set mountains and made grow therein [something] of every beautiful kind,) (Qaaf: 7)

That does not mean that the earth is flat and not round, on the contrary, this verse proves its sphericity because the earth has no end, has no edge, for if it has been of a square, rectangle or a triangle shape, then we would have found an edge and would have fallen of it, or we would have reached its edge, but, if we walk in a straight line we will return back to the same point we started from, this proves its sphericity.
