Earth's Freshwater Cycle

The verses in the Quran describe the hydrological cycle, detailing how rain is sent down from the sky, giving life to the Earth after it has been barren, and how it forms rivers and streams that sustain various ecosystems.

وَأَرْسَلْنَا ٱلرِّيَٰحَ لَوَٰقِحَ فَأَنزَلْنَا مِنَ ٱلسَّمَآءِ مَآءًۭ فَأَسْقَيْنَٰكُمُوهُ وَمَآ أَنتُمْ لَهُۥ بِخَٰزِنِينَ

We send the fertilizing winds; and send down water from the sky, and give it to you to drink, and you are not the ones who store it.

The Holy Quran · Al-Hijr (The Rock) · 15:22

وَأَنزَلْنَا مِنَ ٱلسَّمَآءِ مَآءًۢ بِقَدَرٍۢ فَأَسْكَنَّٰهُ فِى ٱلْأَرْضِ ۖ وَإِنَّا عَلَىٰ ذَهَابٍۭ بِهِۦ لَقَٰدِرُونَ

And We sent down water from the sky in proper quantity, and settled it in the ground, and We are Able to take it away.

The Holy Quran · Al-Muminoon (The Believers) · 23:18

ٱللَّهُ ٱلَّذِى يُرْسِلُ ٱلرِّيَٰحَ فَتُثِيرُ سَحَابًۭا فَيَبْسُطُهُۥ فِى ٱلسَّمَآءِ كَيْفَ يَشَآءُ وَيَجْعَلُهُۥ كِسَفًۭا فَتَرَى ٱلْوَدْقَ يَخْرُجُ مِنْ خِلَٰلِهِۦ ۖ فَإِذَآ أَصَابَ بِهِۦ مَن يَشَآءُ مِنْ عِبَادِهِۦٓ إِذَا هُمْ يَسْتَبْشِرُونَ

God is He who sends the winds. They stir up clouds. Then He spreads them in the sky as He wills. And He breaks them apart. Then you see rain drops issuing from their midst. Then, when He makes it fall upon whom He wills of His servants, behold, they rejoice.

The Holy Quran · Ar-Room (The Romans) · 30:48
