Musannaf Ibn Abi Shaybah 1843 — Sitting with a person in a state

Ibn Sirin said: I was informed that once the Prophet (peace and blessings be upon him) saw Sayyiduna Hudhayfah (may Allah be pleased with him) trying to hide from his sight. The Prophet (peace and blessings be upon him) said: "I did see you." He said: "O Messenger of Allah, I was in a state of major ritual impurity (janabah)." He (peace and blessings be upon him) said: "The believer does not become impure."
