Abstract
Water is the secret of the existence of human, plant and animal life on this earth, because water is the grace of god in the earth.
Islam has urged the preservation, storage and good exploitation of water because water conservation will save water for all and drain it from the most serious environmental issues.
So our choice of the theme was: "Rationalizing water consumption in the modern message and the adult caliphate."
The Prophet (phub) paid attention to water and was a good example for Muslims to use it, he recommended the economy in the use of ablution water or washing even if it is available and encouraged watering, watering, digging wells and stopping them, reducing the charity of water donation, considering it one of the greatest handouts, and developing a generous approach to solve all Water problems that concern farmers in watering the land in his time.
The caliphs urged people to rationalize the use of water by following the Prophet's Year in the rationalization of water consumption and the adult caliphs sought after the opening of the country to many transformations, including digging wells, enacting canals, constructing irrigation canals, repairing agricultural land and providing water.
