Hadith.2599 - Muhammad ibn Muslim narrated from one of the Imams (as) that he was asked about a man entering Ihram in a dirty garment. Imam (as) said: "No, and I do not say it is forbidden, but what I prefer is that he purifies it. Its purification is through washing. A man should not wash the garment in which he enters Ihram until he exits Ihram, even if it becomes dirty, unless it is affected by a state of ritual impurity (janabah) or something similar, in which case he may wash it."
