If One Forgets the Impurity of Something
Issue No.742- If a person forgets that a particular thing is najis, and his wet body or clothes touch that thing and he offers prayer in them, and then recollects this after the prayer, his prayer is correct. However, if his wet body touches a najis object and later he forgets the najāsah and without rinsing the body beforehand performs ghusl and prayer, both the ghusl and prayer are void.
