Al-Muwatta Hadith 31.95 What Is Not Permitted of Free Loans Malik related to me that he had heard that Abdullah ibn Masud used to say, "If someone makes a loan, they should not stipulate better than it. Even if it is a handful of grass, it is usury." Malik said, "The generally agreed on way of doing things among us is that there is no harm in borrowing any animals with a set description and itemisation, and one must return the like of them. This is not done in the case of female slaves. It is feared about that that it will lead to making halal what is not halal, so it is not good. The explanation of what is disapproved of in that, is that a man borrow a slave-girl and have intercourse with her as seems proper to him. Then he returns her to her owner. That is not good and it is not halal. The people of knowledge still forbid it and do not give an indulgence to any one in it."

Then he added, "You are in a country where the practice of Riba (i.e. usury) is prevalent; so if somebody owes you something and he sends you a present of a load of chopped straw or a load of barley or a load of provender then do not take it, as it is Riba."

Prophet Muhammad's Last Sermon This Sermon was delivered on the Ninth Day of Dhul Hijjah 10 A.H in the Uranah Valley of mount Arafat. "O People, lend me an attentive ear, for I don't know whether, after this year, I shall ever be amongst you again. Therefore listen to what I am saying to you carefully and take these words to those who could not be present here today. O People, just as you regard this month, this day, this city as Sacred, so regard the life and property of every Muslim as a sacred trust. Return the goods entrusted to you to their rightful owners. Hurt no one so that no one may hurt you. Remember that you will indeed meet your Lord, and that He will indeed reckon your deeds. Allah has forbidden you to take usury (Interest), therefore all interest obligation shall henceforth be waived... Beware of Satan, for your safety of your religion. He has lost all hope that he will ever be able to lead you astray in big things, so beware of following him in small things. O People, it is true that you have certain rights with regard to your women, but they also have right over you. If they abide by your right then to them belongs the right to be fed and clothed in kindness. Do treat your women well and be kind to them for they are your partners and comitted helpers. And it is your right that they do not make friends with any one of whom you do not approve, as well as never to commit adultery. O People, listen to me in earnest, whorship Allah, say your five daily prayers (Salah), fast during the month of Ramadhan, and give your wealth in Zakat. Perform Hajj if you can afford to. You know that every Muslim is the brother of another Muslim. You are all equal. Nobody has superiority over other except by piety and good action. Remember, one day you will appear before Allah and answer for your deeds. So beware, do not astray from the path of righteousness after I am gone. O People, no prophet or apostle will come after me and no new faith will be born. Reason well, therefore, O People, and understand my words which I convey to you. I leave behind me two things, the Qur'an and my example, the Sunnah and if you follow these you will never go astray. All those who listen to me shall pass on my words to others and those to others again; and may the last ones understand my words better than those who listen to me direcly. Be my witness oh Allah that I have conveyed your message to your people."

Al-Muwatta Hadith 31.84 Usury in Debts
Malik related to me that Zayd ibn Aslam said, "Usury in the Jahiliyya (days of ignorance - prior to Islam) was that a man would give a loan to a man for a set term. When the term was due, he would say, 'Will you pay it off or increase me?' If the man paid, he took it. If not, he increased him in his debt and lengthened the term for him ." Malik said, "The disapproved way of doing things, about which there is no dispute among us, is that a man should give a loan to a man for a term, and then the demander reduce it and the one from whom it is demanded pay it in advance. To us that is like someone who delays repaying his debt after it is due to his creditor and his creditor increases his debt." Malik said, "This is nothing but usury. No doubt about it." Malik spoke about a man who loaned one hundred dinars to a man for two terms. When it was due, the person who owed the debt said to him, "Sell me some goods, whose price is one hundred dinars in cash for one hundred and fifty on credit." Malik said, "This transaction is not good, and the people of knowledge still forbid it." Malik said, "This is disapproved of because the creditor himself gives the debtor the price of what the man sells him, and he defers repayment of the hundred of the first transaction for the debtor for the term which is mentioned to him in the second transaction, and the debtor increases him with fifty dinars for his deferring him. That is disapproved of and it is not good. It also resembles the hadith of Zayd ibn Aslam about the transactions of the people of the Jahiliyya. When their debts were due, they said to the person with the debt, 'Either you pay in full or you increase it.' If they paid, they took it, and if not they increased debtors in their debts, and extended the term for them."
