During the pre-Islamic era of ignorance, there prevailed types of transactions that involved massive oppression and injustice. When Islam came, it established fair sales and forbade whatever involved oppression. Hence, it forbade what involved fraud and ambiguity to stop disagreement and dispute among people, which is one of the Shariah-approved objectives. In this Hadīth, Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (may Allah's peace and blessings be upon him) forbade the Hasāh sale, which was one of the sales practiced by the people of Jāhiliyyah. If the seller or the buyer threw a pebble, that would be a sign of finalizing the sale. It had three forms: First: The seller says to the buyer: I would sell you of these garments that on which the pebble I throw falls; or: I would sell you a piece of this land from here to the part that this pebble reaches. Second: Considering the act of throwing the pebble itself a sale by saying: If you throw the pebble at this garment, it will be sold to you at such-and-such. Third: Saying: You have the option to either accept or reject the sale until I throw this pebble. It was said: It means saying: Throw the pebble and whatever number comes out, I will be entitled to an equal number of dinars or dirhams. All these are forms of invalid sales that entail doing injustice to one of the two parties of the sale. The Messenger of Allah (may Allah's peace and blessings be upon him) also forbade the Gharar sale. Gharar means danger, delusion, and deceit. This is a generalization after a specification, as it includes any sale that involves any kind of deceit, or that which is ambiguous or cannot be fulfilled. One of the rationales behind forbidding this sale is the fact that it is a waste of money, for one may not be able to get the sold item, which means that he spent his money in vain. The Hadīth prohibits deception and fraud in sales. It warns against consuming people's properties wrongfully. It also points out that the object of a sale transaction must be something known and must have a known price..
