The word(s) "rib" appears 143 time(s) in 127 verse(s) in Quran in Mohsin Khan translation.

(11) 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.

(12) Allah will destroy riba (usury) and will give increase for Sadaqat (deeds of charity, alms, etc.) And Allah likes not the disbelievers, sinners.

(13) O you who believe! Be afraid of Allah and give up what remains (due to you) from riba (usury) (from now onward), if you are (really) believers.

(14) O you who believe! When you contract a debt for a fixed period, write it down. Let a scribe write it down in justice between you. Let not the scribe refuse to write as Allah has taught him, so let him write. Let him (the debtor) who incurs the liability dictate, and he must fear Allah, his Lord, and diminish not anything of what he owes. But if the debtor is of poor understanding, or weak, or is unable to dictate for himself, then let his guardian dictate in justice. And get two witnesses out of your own men. And if there are not two men (available), then a man and two women, such as you agree for witnesses, so that if one of them (two women) errs, the other can remind her. And the witnesses should not refuse when they are called (for evidence). You should not become weary to write it (your contract), whether it be small or big, for its fixed term, that is more just with Allah; more solid as evidence, and more convenient to prevent doubts among yourselves, save when it is a present trade which you carry out on the spot among yourselves, then there is no sin on you if you do not write it down. But take witnesses whenever you make a commercial contract. Let neither scribe nor witness suffer any harm, but if you do (such harm), it would be wickedness in you. So be afraid of Allah; and Allah teaches you. And Allah is the All-Knower of each and everything.

(15) And if you are on a journey and cannot find a scribe, then let there be a pledge taken (mortgaging) ; then if one of you entrust the other, let the one who is entrusted discharge his trust (faithfully), and let him be afraid of Allah, his Lord. And conceal not the evidence for he, who hides it, surely his heart is sinful. And Allah is All-Knower of what you do.

(16) Aforetime, as a guidance to mankind. And He sent down the criterion [of judgement between right and wrong (this Qur'an)]. Truly, those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, for them there is a severe torment; and Allah is All-Mighty, All-Able of Retribution.

(17) O you who believe! Eat not riba (usury) doubled and multiplied, but fear Allah that you may be successful.

(18) You shall certainly be tried and tested in your wealth and properties and in your personal selves, and you shall certainly hear much that will grieve you from those who received the Scripture before you (Jews and Christians) and from those who ascribe partners to Allah; but if you persevere patiently, and become Al-Muttaqun (the pious - See V.2:2) then verily, that will be a determining factor in all affairs (and that is from the great matters which you must hold on with all your efforts).

(19) Allah commands you as regards your children's (inheritance): to the male, a portion equal to that of two females; if (there are) only daughters, two or more, their share is two-thirds of the inheritance; if only one, her share is a half. For parents, a sixth share of inheritance to each if the deceased left children; if no children, and the parents are the (only) heirs, the mother has a third; if the deceased left brothers (or sisters), the mother has a sixth. (The distribution in all cases is) after the payment of legacies he may have bequeathed or debts. You know not which of them, whether your parents or your children, are nearest to you in benefit; (these fixed shares) are ordained by Allah. And Allah is Ever All-Knower, All-Wise.

(20) Also (forbidden are) women already married, except those (slaves) whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek (them in marriage) with Mahr (bridal-money given by the husband to his wife at the time of marriage) from your property, desiring chastity, not committing illegal sexual intercourse, so with those of whom you have enjoyed sexual relations, give them their Mahr as prescribed; but if after a Mahr is prescribed, you agree mutually (to give more), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise.
