There is no concept of remaining stagnant in deen. We are either rising or falling, progressing or deteriorating, but we never remain at a constant level of spirituality and devotion. In order to remain afloat in water, we have to do something proactive or else we will sink. Similarly, the greatest benefit of attending gatherings of learning is that they provide the environment, link and connection with the ulama in order to check any decline. We may not necessarily learn something new all of the time, but such gatherings keep us afloat in our religion.
