This is another major sin that is widely spread in our community.
Allah says(interpretation of the meaning):
“Those who eat Riba (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitan (Satan) leading him to insanity. That is because they say: “Trading is only like Riba (usury),” whereas Allah has permitted trading and forbidden Riba (usury). So whosoever receives an admonition from his Lord and stops eating Riba (usury) shall not be punished for the past; his case is for Allah (to judge); but whoever returns [to Riba (usury)], such are the dwellers of the Fire – they will abide therein…” [Al-Baqarah 2: 275-279]
Abu Sa’id Al Khudri narrated that Allah’s Messenger (peace and blessings of Allaah be upon him) said: Gold is to be paid for by gold, silver by silver, wheat by wheat, barley by barley, dates by dates, salt by salt, like by like, payment being made hand to hand. He who made an addition to it, or asked for an addition, in fact dealt in usury. The receiver and the giver are equally guilty. (Muslim)
Abdullah ibn Mas’ud narrated that the Messenger of Allah cursed the one who accepted usury, the one who paid it, the witness to it, and the one who recorded it.” (Abu Dawud)
Abdullah ibn Amr ibn al-‘As narrated that Allah’s Messenger cursed the one who bribes and the one who takes bribe. (Abu Dawud)
…Abide by the truth even though your mind deserts you.
