Is it obligatory to obey the elder brother regarding staying in the shop at the time of the Adhan and missing congregational prayers in the mosque?

If the questioner misses congregational prayer in the mosque because his elder brother prevents him, claiming he must stay in the shop, then it is not permissible for him to obey him in this if he hears the call to prayer. This is because attending congregational prayer is obligatory for him, according to the preponderant opinion, and it is not permissible to miss it except with a legitimate excuse. The brother does not have the right to order him to stay behind, and it is not permissible to obey him in disobeying the Creator. If they cannot attend the congregational prayer except by closing the shop, then it is obligatory for them to close it.
