Is it permissible for a mu'adhdhin in a state of major ritual impurity to enter the mosque to call the adhan and then leave to perform ghusl?

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: If the mu'adhdhin is in a state of janabah, is it permissible for him to enter the mosque to call the adhan and then return to perform ghusl?

Answer:
Yes, except for passersby. If you are , the person in a state of major ritual impurity may enter the mosque, but he does not sit down; he is merely passing through. When he takes something, the Messenger (peace and blessings be upon him) said to 'A'ishah: "Hand me the water skin from the mosque." She said: "I am menstruating." He said: "Your menstruation is not in your hand; the hand is not where the menstruation is." Yes.
