My husband doesnt like me going to seek the knowledge of deen. He says that this is not my priority and that i should look afer the house, child etc.. will it be a sin if i disobey him?

It is farz to seek that amount of knowledge that you may differentiate between halaal and haraam of your daily life. You may read bahisti zewar for basic masail and seek knowledge for necessary laws also through your husband phoning ulamas. Else you may follow basic courses offered by alimas throughout the island.
