The Parable of the Life of this World

Allah tells us that water originates in the sky. This is like the Ayah:

وَأَنزَلْنَا مِنَ السَّمَآءِ مَآءً طَهُوراً

Commentary

The word: يَنَابِيعَ (yanabi in verse 21: فَسَلَكَهُ يَنَابِيعَ فِي الْأَرْ‌ضِ (made it penetrate into the earth [ and gush forth ] in the form of springs) is the plural form of: یَنبُوع (yanbu) which means springs that gush out from the soil. The sense is that the act of sending down water from the sky is by itself a great blessing, but also crucial was the arrangement to conserve it underground. But for this arrangement to save this blessing of water, its users would have derived benefit from it only at the time of rains, or for a few days following it. Although, on water depends their life, and it is the kind of need one cannot stay free from, even for a day. Therefore, Allah Ta’ ala did not consider it sufficient to just send down this blessing, instead, made elaborate and very unique arrangements for its conservation. Some of it gets deposited in ditches, ponds, tanks and reservoirs. Then a huge supply is turned into ice and made to sit on mountain peaks and its ridges, an arrangement that takes care of the danger of water going bad. Then ice melts and water travels through veins in the mountains until it reaches the land and gushes out in the form of streams, all over, on its own, without any human input, and finally finds its way through the land in the form of rivulets and rivers. Rest of the water keeps flowing underground which can be retrieved by digging a well almost anywhere.
