Water should Be Ṭāhir and Unmixed
Issue No.284- There are twelve conditions for the validity of wuḍū: First condition: The water should be ṭāhir. Second condition: The water should be unmixed.Therefore, wuḍū performed with najis or mixed water is void, even if one may not be aware of its being najis or mixed, or may have forgotten about it. And one must repeat prayers performed with such wuḍū.
