The word(s) "sum" appears 37 time(s) in 36 verse(s) in Quran in Muhammad Pickthal translation.

(1) There is no sin for you in that which ye proclaim or hide in your minds concerning your troth with women. Allah knoweth that ye will remember them. But plight not your troth with women except by uttering a recognised form of words. And do not consummate the marriage until (the term) prescribed is run. Know that Allah knoweth what is in your minds, so beware of Him; and know that Allah is Forgiving, Clement.

(2) Would any of you like to have a garden of palm-trees and vines, with rivers flowing underneath it, with all kinds of fruit for him therein; and old age hath stricken him and he hath feeble offspring; and a fiery whirlwind striketh it and it is (all) consumed by fire. Thus Allah maketh plain His revelations unto you, in order that ye may give thought.

(3) O ye who believe! When ye contract a debt for a fixed term, record it in writing. Let a scribe record it in writing between you in (terms of) equity. No scribe should refuse to write as Allah hath taught him, so let him write, and let him who incurreth the debt dictate, and let him observe his duty to Allah his Lord, and diminish naught thereof. But if he who oweth the debt is of low understanding, or weak, or unable himself to dictate, then let the guardian of his interests dictate in (terms of) equity. And call to witness, from among your men, two witnesses. And if two men be not (at hand) then a man and two women, of such as ye approve as witnesses, so that if the one erreth (through forgetfulness) the other will remember. And the witnesses must not refuse when they are summoned. Be not averse to writing down (the contract) whether it be small or great, with (record of) the term thereof. That is more equitable in the sight of Allah and more sure for testimony, and the best way of avoiding doubt between you; save only in the case when it is actual merchandise which ye transfer among yourselves from hand to hand. In that case it is no sin for you if ye write it not. And have witnesses when ye sell one to another, and let no harm be done to scribe or witness. If ye do (harm to them) lo! it is a sin in you. Observe your duty to Allah. Allah is teaching you. And Allah is knower of all things.

(4) And whoso disputeth with thee concerning him, after the knowledge which hath come unto thee, say (unto him): Come! We will summon our sons and your sons, and our women and your women, and ourselves and yourselves, then we will pray humbly (to our Lord) and (solemnly) invoke the curse of Allah upon those who lie.

(5) O ye who believe! Devour not usury, doubling and quadrupling (the sum lent). Observe your duty to Allah, that ye may be successful.

(6) And if ye wish to exchange one wife for another and ye have given unto one of them a sum of money (however great), take nothing from it. Would ye take it by the way of calumny and open wrong?

(7) Lo! Those who disbelieve Our revelations, We shall expose them to the Fire. As often as their skins are consumed We shall exchange them for fresh skins that they may taste the torment. Lo! Allah is ever Mighty, Wise.

(8) Now have ye come unto Us solitary as We did create you at the first, and ye have left behind you all that We bestowed upon you, and We behold not with you those your intercessors, of whom ye claimed that they possessed a share in you. Now is the bond between you severed, and that which ye presumed hath failed you.

(9) They said (unto Pharaoh): Put him off (a while) - him and his brother - and send into the cities summoners,

(10) And Allah summoneth to the abode of peace, and leadeth whom He will to a straight path.
