Who can truly call himself a true believer? He who makes the next world his goal and who is constantly striving to find favour with his Lord. Such a man does not make worldly possessions his aim in life. This does not mean, however, that he renounces the world, for a certain number of material things are an obvious necessity. It simply means that when he makes a living and engages in worldly activities, he does so only in so far as such action is related to acquiring the bare necessities of life. His purpose in life is never to amass wealth. His purpose, on the contrary, is to gain the blessing of his Lord. So, out of whatever he has, he keeps only what he really needs for himself and spends the rest for the cause of God. If we were to attempt to state, in explicit, legal terms, how men should deal with their fellowmen and how they should conduct their business, this would be too complicated in the context of daily living. It is, therefore, more useful to lay down some, fundamental guidelines: to wish others well and to keep in mind not just our own interests, but also the interests of those with whom we have to deal, thinking of them as brothers. God will never take us to task if we act in a manner which is conducive to harmony and justice.
