The Qur'an informs us about what is auspicious and what is beneficial. The most beneficial thing to do is to strive to save the Hereafter of people and to give an intellectual struggle on the way of Allah. Or else it is not to become a businessman and to found holdings and operate touristic facilities and keep one's self with trade as some people claim. This is a highly insincere approach. Happiness comes with faith. - Harun Yahya
