Taleem is the easiest method to bring deen into ur home. If one is not able to make his wife listen to taleem, then i think its a serious issue which needs to be sorted. And lemme tell u the ipod lectures and taleem can never be equal. Listening to lectures on cd players while doing some other work is kinda disrespect to the lectures and their is no Nehj-e-nabwi in the cd player lectures. The virtues of dhikr are regarding to taleem not the one listening to cd players. "maulana saad (d.b) once said before a lecture that Allah's angels surround the gathering present, they dont surround the places where the voice reaches." The ilm obtained by listening to lectures on cd players hardely transforms into ilm-e-nafia. Taleem is the best n the easiet solution.
