وَمَا يَسْتَوِي الْبَحْرَانِ هَٰذَا عَذْبٌ فُرَاتٌ سَائِغٌ شَرَابُهُ وَهَٰذَا مِلْحٌ أُجَاجٌ ۖ وَمِن كُلٍّ تَأْكُلُونَ لَحْمًا طَرِيًّا وَتَسْتَخْرِجُونَ حِلْيَةً تَلْبَسُونَهَا ۖ وَتَرَى الْفُلْكَ فِيهِ مَوَاخِرَ لِتَبْتَغُوا مِن فَضْلِهِ وَلَعَلَّكُمْ تَشْكُرُونَ (12)
(35:12) The two masses of water are not alike. *27 The one is sweet, sates thirst, and is pleasant to drink from, while the other is salt, bitter on the tongue. Yet from both you eat fresh meat, *28 and extract from it ornaments that you wear; *29 and you see ships cruising through it that you may seek of His Bounty and be thankful to Him.
*27) That is, the body of water in the oceans, and the body of water in the rivers and springs and lakes.
*28) "Fresh flesh": Flesh of water animals.
*29) That is pearls and corals and, in some rivers, diamonds and gold.
