Dilemma: You have a thorough bred watch dog at home. She has puppies. You take it to the pet shop and they offer you a high price for each. What do you do?
2:275 (Y. Ali) Those who devour usury will not stand except as stand 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 (for ever).
2:282 (Y. Ali) 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 they 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 take witness 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 God that teaches you. And Allah is well acquainted with all things.
2:283 (Y. Ali) If ye are on a journey, and cannot find a scribe, a pledge with possession (may serve the purpose). And if one of you deposits a thing on trust with another, Let the trustee (Faithfully) discharge His trust, and let him fear his Lord. Conceal not evidence; for whoever conceals it,- His heart is tainted with sin. And Allah Knoweth all that ye do.
24:37 (Y. Ali) By men whom neither traffic nor merchandise can divert from the Remembrance of Allah, nor from regular Prayer, nor from the practice of regular Charity: Their (only) fear is for the Day when hearts and eyes will be transformed (in a world wholly new),-
62:9 (Y. Ali) O ye who believe! When the call is proclaimed to prayer on Friday (the Day of Assembly), hasten earnestly to the Remembrance of Allah, and leave off business (and traffic): That is best for you if ye but knew!
62:10 (Y. Ali) And when the Prayer is finished, then may ye disperse through the land, and seek of the Bounty of Allah. and celebrate the Praises of Allah often (and without stint): that ye may prosper.

Fiqh of Trade
First of all, it is obligatory to know the conditions of a valid sale. these are six:
1. The spoken offer and acceptance. A sale conducted without a spoken offer and acceptance (mu’atah) is therefore invalid in our school, although it is permissible to follow those who hold that it is permissible [h: such as the Hanafis]. Some of our [h: Shafii] Imams have also chosen this position [h: cf. Reliance k1.1 for further detail].
2. The merchandise must be pure. It is therefore invalid to transact something that is impure (such as a dog), although it is permissible to relinquish one’s right (raf’ al-yad) over it in exchange for something, [h: provided that this is done] without the wording of a sale (bay’).
3. The merchandise must be useful. It is therefore invalid, for example, to transact musical instruments, since they are not considered useful from the perspective of Islamic Law and it is forbidden to use them.
4. The seller must own the merchandise. It is therefore invalid [h: for him] to transact something that he does not own.
5. The merchandise must be known. It is therefore invalid to transact something that is unknown in a manner that leads to dispute.
6. The merchandise must be deliverable. It is therefore invalid, for example, to transact something that a third party has wrongfully appropriated when [h: the seller] is unable to take it back from him.
