The World Federation One Stop Fiqh

Ruling 205

If a disbeliever declares in any language the shahādatayn (two testimonies) – i.e. he testifies to the oneness of Allah and to the prophethood of the Seal of the Prophets [Prophet Muḥammad (Ṣ)] – he becomes a Muslim. In the event that he was previously ruled as being impure, then, after becoming a Muslim, his body, saliva, nasal mucus, and sweat are pure. However, if at the time of becoming a Muslim an intrinsic impurity was on his body, it must be removed and that part of his body must be washed; and if the intrinsic impurity was removed before he became a Muslim, then based on obligatory precaution that part of his body must be washed.
