Surah Fatir, verse 12

وَمَا يَسْتَوِى ٱلْبَحْرَانِ هَـٰذَا عَذْبٌ فُرَاتٌ سَآئِغٌ شَرَابُهُۥ وَهَـٰذَا مِلْحٌ أُجَاجٌ ۖ وَمِن كُلٍّ تَأْكُلُونَ لَحْمًا طَرِيًّا وَتَسْتَخْرِجُونَ حِلْيَةً تَلْبَسُونَهَا ۖ وَتَرَى ٱلْفُلْكَ فِيهِ مَوَاخِرَ لِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ ﴿١٢﴾

35:12 The two bodies of water are not alike: one is fresh and palatable, pleasant to drink, and the other is salty and bitter. Yet from each you eat fresh meat and extract ornaments to wear. And you see the ships traverse their way through both, so that you may seek His bounty and so that you may give thanks
