One can turn away from worthless and useless things if one acts in order to gain the good pleasure of Allah alone. Believers know that they need to use the time granted to them in this world in the most efficient way because what they do in the world determines their permanent abode. Therefore, in every deed they perform, they aim to gain a good deed for the Hereafter. Naturally they talk, have fun, eat, laugh, think and work just as everyone else does; but in doing these things they always have good intentions which are likely to be of benefit to other people and to the religion.
