So many social evils can be directly attributed to either some members of society having an insufficient means of livelihood or others having an excess of wealth. Islam urges that one earns one’s livelihood by all possible but lawful means, so that one’s essential needs are properly met on the one hand, and one does not remain dependent on others, on the other. According to the Quran and Hadith, the greed for more and more, niggardliness, holding money back to centralize it in one or a few hands, are the main roots of all criminal and destructive tendencies in human society. That is why virtues such as contentment, moderation, simplicity, altruism, spending on charity and sharing one’s happiness with others are so highly and repeatedly recommended in Islam.
Conversely, vices like extravagance, selfishness, monopolistic practices, exploitation, usury and all unfair means of money-making are strongly condemned and prohibited. How to deal with the problems of earning a livelihood in accordance with the Islamic way of life? The answer to this question may be summed up in the following points:
(a) Avoidance of transgression: God Almighty has declared in the Quran: “Eat of the good things we have given for your sustenance, and do not transgress with respect to them.” (20:81)
(b) Self-reliance: One should try one’s utmost to earn one’s daily bread by one’s own efforts, without being dependent on anybody else. The Prophet Muhammad is reported to have said repeatedly: “The best food one has ever had is that which one has earned with one’s own hands.” (Abu Dawud)
(c) Avoidance of niggardliness and spending in charity: When one is fortunate enough to earn even more than it takes to meet one’s own needs, one should not try to be parsimonious with one’s earnings. Instead, one should rather extend a supporting hand to less fortunate or even destitute members of society. Otherwise, one’s wealth will become a curse for oneself rather than a blessing. Hence, the Prophet Muhammad used to say in his regular prayers: “O God, give a good compensation to one who spends in charity and cause destruction to one who holds his wealth back.” (Nasai)
(d) Contentment: To attain inner peace and real happiness, one has to remain content with what one has been able to earn independently and lawfully. The Prophet Muhammad says in this respect: “Indeed, he has attained eternal success and prosperity who accepted Islam, and God has filled his heart with contentment towards whatever he was given.” He also said: “A little that suffices is much better than a surfeit that causes disturbance.” (Al-Bayhaqi)
(e) Simplicity: Last, but not least, an important Islamic principle concerning one’s livelihood is simplicity. The Prophet’s own lifestyle was a unique example of simplicity. In one of his sayings he has even considered it one of the signs of true faith (Ibn Majah). In another hadith, he warns his companions: “Stay away from the luxurious life. For the servants of God do not indulge in luxury.” (Musnad Ahmad)
