Is it permissible for the mu'adhdhin to miss attending religious lessons for the sake of the adhan?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I am the mu'adhdhin for one of the mosques, and I wish to attend some of the lessons, but the adhan prevents me. Is this excuse a valid reason for missing the religious lessons?

Answer:
Attend the lessons, and when the time for the adhan comes or approaches, go out and head to the mosque to call the adhan. Combine both matters; combine both matters. Unless you are unable to combine them, in which case you prioritize the work you committed to, which is the adhan. Or, if you find a proxy you trust who volunteers to take your place, then you attend the lessons and appoint someone to call the adhan on your behalf. This is cooperation in righteousness and piety.
