Definition and the Ruling of Disappearance of a Muslim
Issue No.242- When a Muslim’s body, clothes or any other thing which is in his possession become najis with him being aware of it, and that Muslim leaves afterwards, if it is probable that he made them ṭāhir, they will be ṭāhir provided that they are things in which ṭahārah is necessary, like clothes in which one performs prayer, or food and utensils.
