Hadith 776
Sayyiduna Muawiyah bin Abu Sufyan (may Allah be pleased with him) narrates that I asked Sayyidah Umm Habibah (may Allah be pleased with her), "Did the Prophet (peace and blessings of Allah be upon him) pray in the garment in which he had been intimate with you?" She replied, "Yes, when he (peace be upon him) did not see any impurity in it (he would perform the prayer in it)." In the narration of Ibn Ishaq, it is stated: "In the garment in which he (peace be upon him) had lain with you (he would pray in it)."
