Ruling 205. If a disbeliever declares in any language the shahādatayn (two testimonies) – i.e. he testifies to the oneness of Allah the Exalted 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 to be impure based on obligatory precaution,[39] 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 is on his body, it must be removed and that part of his body must be washed; and if the intrinsic impurity is removed before he becomes a Muslim, then based on obligatory precaution, that part of his body must be washed.

Ruling 206. If when someone was a disbeliever any clothes of his that were wet made contact with his body – irrespective of whether those clothes were on his body at the time he became a Muslim or not – then based on obligatory precaution, one must avoid them [i.e. they are ruled to be impure].

Ruling 207. If a disbeliever says the shahādatayn but one does not know whether he has sincerely become a Muslim or not, he is pure. The same applies if a disbeliever says the shahādatayn and one knows he has not sincerely become a Muslim but he does not do anything that contradicts his saying of the shahādatayn.
