" He who buys a goat has the option...."

Out of the ahadith which Abu Huraira (Allah be pleased with him) reported to us from Allah's Messenger (ﷺ) one is this that Allah's Messenger (ﷺ) said: If one among you buys a she-camel having its udder tied up he has the two options for him after milking it either (to retain it) or return it with a sa' of dates.

He who buys food-rain should not sell it until he has taken possession of it. Ibn Abbas (Allah be pleased with them) said: I regard everything like food (so far as this principle is concerned).

He who buys foodgrain should not sell that before taking possession of it. He (the narrator) said: We used to buy foodgrain from the caravans in bulk, but Allah's Messenger (ﷺ) forbade us to re-sell that until we had shifted it to some other place.

Ibn 'Umar (Allah be pleased with them) reported that they were beaten during the lifetime of Allah's Messenger (ﷺ) if they had bought foodgrains in bulk and then sold them in the spot without shifting them (to some other place).

Have you made lawful the transactions involving interest? Thereupon Marwan said: I have not done that. Thereupon Abu Huraira (ﷺ) said: You have made lawful the transactions with the help of documents only, whereas Allah's Messenger (ﷺ) forbade the transaction of foodgrains until full possession is taken of them. Marwan then addressed the people and forbade them to enter into such transactions (as are done with the help of documents). Sulaiman said: I saw the sentinels snatching (these documents) from the people.

When you purchase foodgrains, do not sell them until you have taken possession of them.

This hadith has been narrated on the authority of Ibn 'Umar (Allah be pleased with them) through another chain of transmitters.

When two persons enter into a transaction, each of them has the right to annul it so long as they are not separated and are together (at the place of transaction) ; or if one gives the other the right (to annul the transaction) But if one gives the other the option, the transaction is made on this condition (i. e. one has the right to annul the transaction), it becomes binding. And if they are separated after they have made the bargain and none of them annulled it, even then the transaction is binding.

There is no transaction between two persons entering a transaction until they separate, but only when there is an option to annul it.

A man mentioned to the Messenger of Allah (ﷺ) that he was deceived in a business transaction, whereupon Allah's Messenger (ﷺ) said: When you enter into a transaction, say: There should be no attempt to deceive.

Another chain on the authority of Ibn 'Umar narrated the same as the above hadith.

Ibn 'Umar (Allah be pleased with them) reported that Allah's Messenger (ﷺ) forbade the sale of palm-trees (i. e. their trults) until the dates began to ripen, and ears of corn until they were white and were safe from blight. He forbade the seller and the buyer.

This hadith is reported or the authority of Yahya with the same chain of transmitters up to" until its good condition becomes clear," but lie did not mention what follows (these words).

I asked Ibn 'Abbas (Allah be pleased with them) about the sale of dates. He said: Allah's Messenger (ﷺ) forbade the sale of dates of the trees until one eats them or they are eaten (i. e. they are fit to be eaten) or until they are weighed (or measured). I said: What does it imply:" Until it is weighed"? Thereupon a person who was with him (Ibn Abbas) said: Until he is able to keep it with him (after plucking them).

Do not buy the fruit until their condition is clear, and do not buy the fresh dates. A hadith like this has been reported by Ibn 'Umar through another chain of transmitters.

Zaid b. Thabit (Allah be pleased with him) reported Allah's Messenger (may peace he upon him) having given concession in case of 'ariyya for selling dry dates (with) fresh dates after measuring them out.

Zaid b. Thabit reported that Allah's Messenger (ﷺ) give concession in case of 'ariyya transactions according to which the members of the household give dry dates according to a measure and then eat fresh dates (in exchange for it)

'Ariyya implies that a person should buy fresh dates on the tree for his family to eat against a measure of dry dates.

Nafi, reported this hadith with the same chain of transmitters stating that Allah's Messengtr (ﷺ) granted concession in case of 'ariyya transactions (for exchange of the same commodity) with measure.
