Is Rainwater Drinkable According To Quran?
This is neither subject of Quran nor is it mentioned anywhere in Quran. This is a matter of science and scientists/doctors should be consulted whether rainwater is drinkable or not. Some verses are wrongly interpreted to support this point (e.g. Quran 25:48-49 AND Quran 50:9 ) coupled with few fabricated Ahadith in this regard. As a general principle, normally you could drink rainwater without becoming ill. However, rainwater contains pollutants, soil, plant parts, insect parts, bacteria, algae, and sometimes radioactive materials that the rain/snow has washed out of the air. If filtered with one of the filtering systems that you can buy in stores nowadays, and then boiled, you could probably drink the water safely. However, it is safer yet to get your water from municipal water supplies or from wells that are frequently tested.
