Why Is It Permissible to Use Water Mixed with Soap for Wudu?

Answered by Ustadh Sufyan Qufi


In Mukhtasar Quduri and other books it says it is permitted to do wudu with water mixed with soap or saffron. However i have also read that wudu is not permitted with water in which one or two attributes have changed. Surely water mixed with soap or saffron would change the colour and taste, and probably smell. Could you please clarify how to understand this? Jazakallah khair.


I pray this finds you in the best of states.
Soap and saffron are solid. Thus, when water is mixed with these solids, as long as this water retains its flowing quality, it remains unconditioned and usable for ritual purification. [Shurunbulali, Nur al-Idah]

Changes in color, smell, or taste are of no consequence when it comes to solids.
It is only when the mixed water becomes too viscous and sticky to flow that this water will lose its purifying quality. [ibid]

The reason for this ruling is that it is impossible to prevent water from being mixed with foreign elements. Thus, as long as mixed water can still be called “water,” it retains its purifying quality. Soapy water and Saffron water are still called water just like spring water and well water are still called water despite all the dirt in them. [Marghinani, Hidaya]

Allah, Most High, says: “It is not Allah’s Will to burden you, but to purify you and complete His favour upon you, so perhaps you will be grateful.” [5.6]

Water mixed with liquids

The criteria you have mentioned in your question apply only to water mixed with liquids (such as milk or vinegar). It is only when water is mixed with a liquid that the changes in color, smell, or taste will be of significance in removing the purifying quality of water. [Shurunbulali, Nur al-Idah]   

And Allah knows best.
