The Sahabah (may Allah be pleased with them) had the greatest respect for the Prophet (blessings and peace of Allah be upon him). Some of them viewed janabah as a very serious matter, and regarded it as a kind of physical impurity, so they would not like to sit with the Prophet (blessings and peace of Allah be upon him) or touch him when they were in that state. But the Prophet (blessings and peace of Allah be upon him) explained to them the correct view concerning that matter, and that the believer never becomes impure (najis), even if he is junub, as referred to in this hadith. Abu Hurayrah (may Allah be pleased with him) tells us that the Prophet (blessings and peace of Allah be upon him) met him in one of the streets of Madinah when he was junub. This word refers to anyone who emits maniy (semen) or has intercourse with his wife; it is so called because he must avoid (ijtinab) prayer and other acts of worship until he has purified himself. So Abu Hurayrah turned back after meeting the Prophet (blessings and peace of Allah be upon him), without speaking to him or greeting him; he went and did ghusl and purified himself, removing the state of janabah and major impurity, then he came back to the Prophet (blessings and peace of Allah be upon him), who asked him why he had disappeared and hidden in a manner that was not normal in his case. Abu Hurayrah told him that he had refused to meet the Prophet (blessings and peace of Allah be upon him) because he believed that if the Muslim is junub, he has become impure (najis). The Prophet (blessings and peace of Allah be upon him) was surprised by Abu Hurayrah’s thinking and what he believed, for janabah only prevents a person from praying, touching the Mus-haf and entering the mosque; it does not prevent him from sitting with other Muslims or meeting them, and the one who is junub does not become impure in a literal sense. The Prophet (blessings and peace of Allah be upon him) told him that the Muslim does not become impure and that he is not filthy, meaning that when the Muslim is not in a state of purity (taharah), he is impure according to Islamic rulings, but he is not impure in a real sense, so he himself does not become najis because of the impurity that happened to him in his body. The description of him being impure is just a ruling that the Lawgiver applies to the body, so janabah prevents him from doing some things, such as praying and reading Qur’an. As for sitting with other people and interacting with them, that is not included among the things that are not allowed when one is junub. The believer is pure (tahir) in and of himself always, whether he is junub or not..
