The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Earning an honest living is a duty next to the principal duties of Eeman.” [Bayhaqi]
One day a woman came to Imam Abu Hanifah with a length of silk which she wanted him to sell for her and quoted a hundred dirhams for it. On the Imam expressing surprise at that figure, she raised it to two hundred. But the Imam told her that it was worth not less than five hundred. “Are you making fun of me?” said the woman. The Imam took out five hundred, gave them to her and kept the cloth. This kind of scrupulous honesty, far from harming his business, made it flourish. [Sirat-i-Numan]
Not only has Allah (subhana wa ta’ala) required Muslim men to work to support themselves and their dependents but it must be through honest means only. Working is a religious obligation and the person will be rewarded by Allah (subhana wa ta’ala) for bowing down to His commands. As for his income, a person will only make what has already been destined for him, so all the more reason to stick to honesty.
