a person gets up from sleep, performs Wudu' (ablution), and offers Salah (Prayer) then, on his return to bed to resume sleeping, he finds traces of impurity on the bed e.g. Urine,
what should he do after praying in his nightwear which is now doubted?
As Taharah (ritual purification) is the original case, accidental doubts count for nothing after that.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
