Believers know that they should use their time wisely and not waste it on worthless things. They use their conscience and reason to distinguish between useful and useless matters, and aim to gain Allah's approval in all of their deeds. Consequently, when they hear anything that is not relevant to the benefit of the religion and of Muslims, they turn away and refuse to engage in it.
