Water and life
"And have you seen the water that you drink?" (56:68). These verses turn the most ordinary act of the day into a question: who brought it down, and who keeps it sweet?
أَوَلَمْ يَرَ ٱلَّذِينَ كَفَرُوٓا۟ أَنَّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَٰهُمَا ۖ وَجَعَلْنَا مِنَ ٱلْمَآءِ كُلَّ شَىْءٍ حَىٍّ ۖ أَفَلَا يُؤْمِنُونَ٣٠
Transliteration: awalam yara alladhīna kafarū anna l-samāwāti wal-arḍa kānatā ratqan fafataqnāhumā wajaʿalnā mina l-māi kulla shayin ḥayyin afalā yu'minūna
Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
أَفَرَءَيْتُمُ ٱلْمَآءَ ٱلَّذِى تَشْرَبُونَ٦٨ ءَأَنتُمْ أَنزَلْتُمُوهُ مِنَ ٱلْمُزْنِ أَمْ نَحْنُ ٱلْمُنزِلُونَ٦٩ لَوْ نَشَآءُ جَعَلْنَٰهُ أُجَاجًا فَلَوْلَا تَشْكُرُونَ٧٠
Transliteration: afara-aytumu l-māa alladhī tashrabūna · a-antum anzaltumūhu mina l-muz'ni am naḥnu l-munzilūna · law nashāu jaʿalnāhu ujājan falawlā tashkurūna
And have you seen the water that you drink? Is it you who brought it down from the clouds, or is it We who bring it down? If We willed, We could make it bitter, so why are you not grateful?
Translation: Saheeh International
Meccan (Sura al-Anbiyāʾ).
"And have you seen the water that you drink? Is it you who brought it down from the clouds, or is it We who bring it down? If We willed, We could make it bitter, so why are you not grateful?" (56:68–70), Meccan (Sura al-Wāqiʿa).
Key words
Jaʿalnā min al-māʾi kulla shayʾin ḥayy: "made from water every living thing". Al-muzn (56:69): rain-clouds. Ujāj (56:70): bitter, salty water that cannot be drunk.
Setting
21:30 is part of an argument addressed to those who deny God: the heavens, the earth and life itself point to their Maker. 56:68–70 is the third of four questions in Sura al-Wāqiʿa about what sustains us: the seed (56:63–64), the water (56:68–70), the fire (56:71–72), after the creation of the human being (56:58–59). Each asks who really provides it.
This page and S24
The first half of 21:30 ("joined entity… separated") is discussed on S24. This page is about its second half and about drinking water.
And have you seen the water that you drink?
56:68
Classical tafsir
Ibn Kathir on 21:30. "meaning, the origin of every living thing is in water". He reads the verse as an argument from what anyone can see: rain, growth and life depend on water.
Al-Jalālayn on 21:30. "in other words water is the cause of such things having life". Where Ibn Kathir speaks of origin, al-Jalālayn speaks of cause: life depends on water.
Ibn Kathir on 56:68–70. Al-muzn means "clouds, according to Ibn ʿAbbas, Mujahid and others". "Allah is stating that indeed He is the One Who causes the rain to fall". "Bitter" (ujāj) means "salty, sour, undrinkable and unfit for growing plants". And the question "why are you not grateful?" asks: "why do you not appreciate the favor Allah does for you by sending down the rain fresh, ready to consume".
What they did not say. Neither commentary reads "made from water every living thing" as a statement about the origin of life in the modern biological sense, or about the chemistry of cells.
How it works
Text version
When seawater evaporates, the salt stays behind; the vapour that forms clouds is fresh water. That is why rain is drinkable and the sea is not (USGS).
- "Every living thing" and water. Established "Up to 60% of the human adult body is water" (USGS). By organ: "the brain and heart are composed of 73% water, and the lungs are about 83% water"; skin is about 64%, muscles and kidneys 79%, bones 31% (USGS, citing Mitchell and others, 1945). Babies are born at about 78% water, falling to about 65% by age one (USGS, citing Dr Jeffrey Utz).
- "Is it you who brought it down from the clouds?" (56:69). Established When seawater evaporates, the salt stays behind; the vapour that forms clouds is fresh. Rain is distilled water, which is why rain is drinkable and the sea is not.
- "We could make it bitter" (56:70). Established Salt water is heavier: "ocean water, which contains dissolved salt, is denser than pure water" (USGS, "Water Density").
- Water's unusual behaviour. Established Most substances shrink when they freeze. Water does the opposite: "Upon freezing, the density of ice decreases by about 9 percent" (USGS). Water is densest at about 4 °C, so near-freezing water is lighter and stays on top, where ice forms; otherwise, USGS notes, "the lake could freeze from the bottom up". Ice floating on top insulates the water below, where fish and plants survive the winter. (This is a fact about water that supports life; the verses do not mention it.)
Points of awe
Reflection
"And have you seen the water that you drink?" (56:68). We drink without looking. The verse asks us to look.
Then it asks three questions. Who brought it down from the clouds? Who keeps it sweet? And why are we not grateful? Ibn Kathir hears in the last question a reproach and an invitation: to "appreciate the favor" of rain sent down "fresh, ready to consume".
Every glass of water has a long story. It was salt water once, or ice, or a cloud. It rose, it fell, it ran through soil and stone. Somewhere along the way the salt was left behind, and what reached your glass could keep you alive. You did none of that.
21:30 widens the view: "made from water every living thing". Ibn Kathir reads it as origin, al-Jalālayn as cause. Either way, life on earth depends on something we receive and cannot make.
The verses do not ask for a lecture on chemistry. They ask for a habit: to drink, and to know that it was given. A person who notices that every day is learning gratitude, and gratitude is where the Quran wants these questions to lead.
Questions readers ask next
Does the verse mean all life is made of water?
Ibn Kathir reads it as "the origin of every living thing is in water"; al-Jalālayn as water being "the cause of such things having life". The biology of water in living things is in "How it works".
Is this verse about the Big Bang?
Its first part ("joined entity… separated") is discussed on S24. This page is about water and life.
Why is rain fresh when the sea is salty?
When water evaporates, the salt is left behind. Clouds are made of fresh water vapour, so rain is fresh.
What does ujāj ("bitter") mean?
Ibn Kathir: "salty, sour, undrinkable and unfit for growing plants".
Why does ice float, and why does it matter?
Ice is about 9% less dense than liquid water (USGS), so lakes freeze from the top, and the ice shelters the water and the life below.
