﴿ أَمَّن جَعَلَ ٱلْأَرْضَ قَرَارًۭا وَجَعَلَ خِلَٰلَهَآ أَنْهَٰرًۭا وَجَعَلَ لَهَا رَوَٰسِىَ وَجَعَلَ بَيْنَ ٱلْبَحْرَيْنِ حَاجِزًا ۗ أَءِلَٰهٌۭ مَّعَ ٱللَّهِ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ ﴾

“Nay - who is it that has made the earth a fitting abode [for living things], and has caused running waters [to flow] in its midst, and has set upon it moun­tains firm, and has placed a barrier between the two great bodies of water? Could there be any divine power besides God? Nay, most of those [who think so] do not know [what they are saying]!”

(Is not He (best) Who made the earth a fixed abode, and placed rivers in the folds thereof) in the middle thereof, (and placed firm hills therein) on earth, (and hath set a barrier) preventing mixture (between the two seas) the sweet and salty seas? (Is there any God beside Allah) who has done this? (Nay, but most of them know not) most of them believe not!
