Doubting If a Part of Wuḍū Has Been Made Ṭāhir
Issue No.300- If one of the parts of wuḍū was previously najis, and after performing wuḍū, one doubts whether he rinsed it before wuḍū or not, his wuḍū will be valid. However, he should rinse it for prayer and if anything comes in contact with it, it should be made ṭāhir.
