والوضوء بالمياه المغصوبة
Ablution with usurped water combines the ritual act of purification with an unlawful use of someone else’s property.
The physical and ritual conditions of ablution may be fulfilled while the taking and use of the water are sinful. Legal theory thus distinguishes ritual consequence from violation of property rights.
This distinction does not permit taking another’s water. The wrong of usurpation and the owner’s claim remain; the specific question concerns whether the purification itself has its usual effect.
