The Holy Quran 35:12 — Surah Fatir
Arabic text
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
Translation
The two water masses (oceans and rivers/lakes) are not the same. The one (river/lake fresh water) is sweet (drinkable), quenching and easy to drink, while the other (seawater) is salty and bitter. (Nevertheless,) From each of these (masses of water) you eat fresh meat (fish) and you extract jewels (pearls) that you wear. You will see ships cleaving (through the waters because Allaah had made them useful to you) so that you seek from Allaah's bounty (your livelihood) and (so that you) show gratitude (to Him for this bounty).
Tafsir (excerpt) — Tafsir Usmani
An example of disbelief and Islam from the phenomena of nature: from the beginning [of the surah] proofs of tawhid (the oneness of Allah) and evidences of [His] power have been set forth, and along with them subtle hints are also being given towards the victory of Islam.
