Is it permissible for a man to perform Salah (prayer) in the same garment he was wearing while having sexual intercourse with his wife?
There is no blame in doing so as long as his clothes are not soiled with impurities, such as urine or Madhy (thin white viscid fluid secreted due to sexual thoughts or desire). Otherwise, he is not allowed to perform Salah in these clothes until he washes them. Maniy (semen) is not impure according to the soundest opinions of scholars. (Part No. 6; Page No. 207) Moreover, it is desirable to wash clothes soiled with Maniy if it is wet, and to rub them if it becomes dry. If clothes are soiled with Madhy discharge, sprinkling them with water will be enough.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
