"... And we give you to drink fresh water?" (Surah Al Mursalat, 77:27)
"He is already down water from the sky for you, and some of it you drink (fertilize) grows plants, which in (the growth of) you graze your herds (Surah An-Nahl, 16:10)
As we have seen, rain water comes from evaporation of water and 97% is salty sea water evaporation. However, rain water is fresh. Rain water is fresh because of the physical processes that have been established by God. Based on this sunnatullah, wherever arising, the evaporation of water, either from the salty sea water, or from lakes that contain a lot of minerals, or from the mud, the water that evaporates never contain any other ingredients of origin.
Rainwater will fall to the ground in a state of pure and clean, in accordance with the provisions of God: ".... We send down from the sky water very clean." (Surat al-Furqan 25:48).
Most holy God with all kalamnya
