Interest means taking the money lent to someone back at the end of certain period and by adding some money to the initial capital. It is illegal, unreturned, and unmerited extra money that is paid by debtor to creditor compulsorily. It means having an unearned gain without turning an honest penny and exerting efforts. It means turning the trouble of people who are in need into opportunity.
Islam declares all kinds of interest as haram definitely. It considers the operations with interest as one of the greatest sins. However, the Almighty Allah (swt) warns believers in the verse I recited in the beginning of my khutbah as follows, “O ye who believe! Devour not usury, doubled and multiplied; but fear Allah that ye may (really) prosper.”1
Although a person who makes operations with interest thinks that he makes profit effortlessly and easily, in fact, he is deemed to lose. However, the Almighty Allah (swt) points out this fact in the Holy Qur’an as follows, “Allah will deprive usury of all growth but will give increase for deeds of charity, for He loveth not creatures ungrateful and wicked.”2 Because the property of those who give zakat and sadaqah gets baraqah and increases. They benefit from their wealth. Their hearts are filled with peace and their book of deeds is filled with rewards. Interest, on the contrary, eliminates the baraqah of a wealth. Its owner cannot make any profit out of it other than sins. It sets up the bankruptcy of its owner both spiritually and materially. The Messenger of Allah (saw) expressed that interest made its owner lose eventually as follows, “Those who increase their property by way of interest cannot benefit from their property.”3
The frustration to be faced by those who do not give up on interest despite all the warnings from our religion is informed in the Holy Qur’an as follows, “Those who devour usury will not stand except as stands one whom the Evil One by his touch hath driven to madness, that is because they say: ‘Trade is like usury’…”4
Then, let us stay away from the disaster of interest which has been one the biggest means of exploitation and oppression in economic life throughout the history. Let us understand that we cannot benefit from the property gained by interest. In this temporary world life, let us try to earn halal money and spend it for halal ways rather than trying to earn more money. Let us always remember that we will not be able to leave the presence of Allah (swt) before accounting for how we earned and for what we spent our property, on the Day of Judgment.
I would like to conclude my khutbah with this warning of Allah the Exalted (swt), “O ye who believe! Fear Allah and give up what remains of your demand for usury, if ye are indeed believers. If ye do it not, take notice of war, from Allah and His Messenger: But if ye turn back, ye shall have your capital sums; deal not unjustly, and ye shall not be dealth with unjustly.”5
