Those who devour usury will not stand except as stands one whom the Evil One by his touch hath driven to madness. That is because they say: "Trade is like usury," but Allah hath permitted trade and forbidden usury. Those who after receiving direction from their Lord, desist, shall be pardoned for the past; their case is for Allah (to judge); but those who repeat (the offence) are Companions of the Fire; they will abide therein (forever). (Al-Baqarah: 275)

O ye who believe! When ye deal with each other, in transactions involving future obligations in a fixed period of time, reduce them to writing let a scribe write down faithfully as between the parties; let not the scribe refuse to write: as Allah has taught him, so let him write. Let him who incurs the liability dictate, but let him fear his Lord Allah, and not diminish aught of what he owes. If the party liable is mentally deficient, or weak or unable himself to dictate, let his guardian dictate faithfully. And get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. The witnesses should not refuse when they are called on (for evidence). Disdain not to reduce to writing (your contract) for a future period, whether it be small or big: it is juster in the sight of Allah, more suitable as evidence, and more convenient to prevent doubts among yourselves but if it be a transaction which ye carry out on the spot among yourselves there is no blame on you if ye reduce it not to writing. But neither take witnesses whenever ye make a commercial contract; and let neither scribe nor witness suffer harm. If ye do (such harm), it would be wickedness in you. So fear Allah; for it is Allah that teaches you. And Allah is well acquainted with all things. (Al-Baqarah: 282)

We have made the Night and the Day as two (of Our) Signs; the Sign of the Night have We obscured, while the Sign of the Day We have made to enlighten you; that ye may seek bounty from your Lord, and that ye may know the number and count of the years: all things have We explained in detail. (Al Israa': 12)

Their covenants (covering) journeys by winter and summer. (Quraish: 2)

Behold! In the creation of the heavens and the earth; in the alternation of the Night and the Day; in the sailing of the ships through the Ocean for the profit of mankind; in the rain which Allah sends down from the skies, and the life which He gives therewith to an earth that is dead; in the beasts of all kinds that He scatters through the earth; in the change of the winds and the clouds which they trail like their slaves between the sky and the earth, (here) indeed are Signs for a people that are wise. (Al-Baqarah: 164)

It is He Who has made the sea subject, that ye may eat thereof flesh that is fresh and tender, and that ye may extract therefrom ornaments to wear, and thou seest the ships therein that plough the waves, that ye may seek (thus) of the bounty of Allah and that ye may be grateful. (An-Nahl:14)

Your Lord is He that maketh the Ship go smoothly for you through the sea, in order that ye may seek of His bounty: For He is unto you Most Merciful. (Al-Israa':66)

Among His Signs is this, that He sends the Winds, as heralds of Glad Tidings, giving you a taste of His (Grace and) Mercy, that the ships may sail (majestically) by His Command and that ye may seek of His Bounty: in order that ye may be grateful. (Ar-Rum:46)

Nor are the two bodies of flowing water alike, the one palatable, sweet, and pleasant to drink, and the other, salt and bitter. Yet from each (kind of water) do ye eat flesh fresh and tender, and ye extract ornaments to wear; and thou seest the ships therein that plough the waves, that ye may seek (thus) of the Bounty of Allah that ye may be grateful. (Fatir:12)

And come not nigh to the orphan's property, except to improve it, until he attains the age of full strength; give measure and weight with (full) justice; no burden do We place on any soul, but that which it can bear, whenever ye speak, speak justly, even if a near relative is concerned; and fulfil the Covenant of Allah: thus doth He command you, that ye may remember. (Al-An'am: 152)

"Give just measure, and cause no loss (to others by fraud). (Shu'araa:181)

"And weigh with scales true and upright.(Shu'araa:182)

"And withhold not things justly due to men, nor do evil in the land, working mischief. (Shu'araa:183)

In order that ye may not transgress (due) balance. (Ar-Rahman:8)

So establish weight with justice and fall not short in the balance. (Ar-Rahman:9)

O ye who believe! eat not up your property among yourselves in vanities: but let there be amongst you traffic and trade by mutual good-will: nor kill (or destroy) yourselves: for verily Allah hath been to you Most Merciful! (An-Nisaa:29)
