Making Wudu (Ablution) without Wasting Water
How to perform ablution (wudu) effectively without wasting water?
In the name of Allah, We praise Him, seek His help and ask for His forgiveness. Whoever Allah guides none can misguide, and whoever He allows to fall astray, none can guide them aright.
It is not permissible to be wasteful in using water for either wudu or ghusl (full ritual bath), as the Prophet (peace be upon him) prohibited it. The Prophet (peace be upon him) would perform wudu using a Mud (a dry measure of half bushel, 543 grams) of water and would perform Ghusl using a Sa`. He (peace be upon him) prohibited using water wastefully.
