Hadith 8:2212
Abu Bakr narrated to us, he said: Jarir narrated to us, from Mughira, from Ibrahim, who said: There is no harm in the *muhrim* (a person in the state of ihram) bathing without being in a state of *janaba* (major ritual impurity), and he may wash his clothes.
حدثنا أبو بكر قال حدثنا جرير عن مغيرة عن إبراهيم قال لا بأس أن يغتسل المحرم من غير جنابة ويغسل ثيابه
