[2/95] al-Istibsar: From al-Mufid from Ja’far b. Muhammad from his father from Sa’d b. Abdallah from Ahmad b. Muhammad from al-Hasan b. Mahbub from Abdallah b. Sinan who said: my father asked Abi Abdillah عليه السلام while I was present [the following question]: I sometimes lend my clothes to a Dhimmi and I know that he drinks wine and eats the meat of swine, so when he returns them to me should I wash them before praying in them? Abu Abdillah عليه السلام said: pray in them and do not wash them because of that, for you lent them to him while you were certain that they were pure and you do not have certainty about its impurity (when he returns them), so there is no harm in you praying in it until you become certain that it is impure.
