Water is one of the greatest blessings of Allah bestowed upon all existence, in particular the mankind. Water is the source of life. Life without water cannot be. Allah has explained this clear in the Quran.
The Quran specifically mentions water as the basic element of life. Indeed, life without water on earth today is unimaginable. Allah says in the Quran:
''... And We made from water every living thing.'' (Surah al-Anbiya verse 30).
In another verse:
''Allah created every living creature from water.'' (Surah an-Nur verse 45).
This means that the whole universe is water. Scientific experiments have shown that. Scientists say that water is the main element of the human body, accounting for seventy-six percent. Water is also the main element of all other living things. Herbs also cannot be imagined without water. One kilogram of sugar requires one thousand liters of fresh water and one kilogram of wheat requires one and a half thousand liters of water to produce. The same is true of industry. For example, it takes four liters of water to produce one kilogram of steel, and so on.
In Islam, water is a great blessing from Allah and should not be wasted or polluted. The previous generations of the Islamic Ummah have become so attentive to water that even our scholars have opened chapters in fiqh books entitled "Don't waste water even on the sea." The following hadith is based on this judgment.
Rasulullah (peace and blessings of Allah be upon him) was very economical in performing ablution and bathing. We the believing slaves should follow the example of Muhammad Mustafa (peace and blessings of Allah be upon him) in the efficient use of water as in all things.
Abdullah bin Umar:
The Messenger of Allah (peace and blessings of Allah be upon him) passed by Sa'd when he was performing ablution, and he said: 'What is this extravagance?' He said: 'Can there be any extravagance in ablution?' He said: 'Yes, even if you are on the bank of a flowing river.'"
As is known, ghusl and ablution are fard prayers for Muslim slaves. Since it is not permissible to waste in such things, it is not possible in other matters that are not worship. But when we look at the realities of life, we see the opposite: overuse of water, instead of saving as much as possible.
