Those who devour usury will not stand except as stands one whom the devil by his touch has driven to madness. That is because they say: Trade is like usury: but Allah has permitted trade and forbidden usury....

Allah will deprive usury of all blessing, but will give increase for deeds of charity, for He loves not any ungrateful sinner....

O you who believe, fear Allah and give up what remains of your demand for usury, if you are indeed believers. If you do it not, take notice of war from Allah and His messenger, but if you repent you shall have your capital sums; deal not unjustly, and you shall not be dealt with unjustly.

And if the debtor is in difficulty, grant him time tin it is easy for him to repay. But if you remit it by way of charity, that is best for you if you only knew.

[Surah al Baqarah, verses 275-280]

His character and morality (Akhlaaq) is the Quraan personified
