Question Summary:
Maa mustaa’mal

Question Detail:

while performing wadu, I keep the tap flowing and take water from it with my hands. And use that water for washing the parts of my body which are required to be washed during wadu. As the water is flowing from the tap, and falls in the Jug below, the said water gets my touch befor falling into the jug.
Can I use the water that has fallen into the jug for washing my feet?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
The water that touches your body during wudhū becomes Musta’mal (used) as soon as it leaves your body and flows away.[1] The ruling regarding such water is that it is clean (Tāhir) but may not be used for wudhū or ghusl.[2] If you have placed a jug under the tap in order to collect the pure water that flows directly from the tap and if any used water from your body falls into that jug, then if the used water is equal to or more than the pure water, the water will not be fit for washing your feet. However, if the used water is less, than it is permissible to use that water for washing the feet.[3] You may determine which of the two is more by estimate.
An alternative and better practice for saving water would be to perform wudhū using a bucket and jug rather than using the tap.
