Our sublime religion Islam commands that we earn our income in halal and legitimate ways. It bans any transaction in which Allah’s (swt) pleasure, human rights, and halal-haram sensitivity are not observed. In this regard, Allah the Almighty (swt) states in the verse I have recited at the beginning of the khutbah as follows, “O you who have believed! Do not consume one another’s wealth unjustly but only [in lawful] business by mutual consent, and do not kill yourselves [or one another]. Indeed, Allah is to you ever Merciful.”
The most important principles of business ethics, according to Islam, are integrity and honesty. A Muslim is someone from whose hands and tongue others are safe. A Muslim is someone who always instills trust in others about their affairs and business. They know that they will earn the pleasure of Allah (swt) to the extent that they are down-to-earth and honest, whether they are selling or buying something. They never resort to lies and deceptions. It is because the wealth obtained through dishonesty and deception brings no benefit.
The Prophet Muhammad (saw) states in one hadith as follows, “An honest and trustworthy merchant will be with the prophets, the righteous, and the martyrs on the Day of Judgment.” So, let us not neglect our life in the Hereafter while earning our living in this temporary world. Let us be certain that not even a morsel-sized haram enters our mouths. May divine blessings abound in our homes and on our plates. May our ethics be founded on non-wastefulness, moderation, gratitude and contentedness.
