Explanation of the author's statement: "And that the price must be known."
Machine translationRead the Arabic original
The Shaykh : Then he said, "And that the price must be known". This is the seventh condition: that the price must be known. So what is the difference between the item sold and the price? It is said that the price is what is in the form of the two currencies (gold and silver). So if I say, "I sold you this cloth for a dirham," what is the price? Yes?
The questioner : ... .
The Shaykh : All right, and if I said, "I sold you the dirham for a cloth"?
The questioner : The cloth.
The Shaykh : No, the price is the dirham.
The questioner : ... .
The Shaykh : O our brothers, we said that some scholars state that the price is the dirhams and dinars. If I say, "I sold you this dirham for a cloth," what is the price? The dirham. And some scholars said that the price is what follows the preposition "ba" (for). So if I say, "I sold you a cloth for a dirham," what is the price? I sold you a dirham for a cloth.
The questioner : The cloth.
The Shaykh : All right, I sold you a pen for a watch?
The questioner : The watch.
The Shaykh : I sold a watch for a pen?
The questioner : A pen.
The Shaykh : That is complete, and this is the most apparent view, even in the custom of people, that the price is what follows the preposition "ba" (for). It is required that the price be known, just as we required that the item sold be known. What is the evidence? The hadith of Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him)Sunan Abi Dawud 3376Sahih (Al-Albani) This is the evidence. And because it is one of the two exchanges, knowledge of it is required, just as knowledge of the other exchange is required. I only said this by way of analogy because there are hadiths regarding the specific item sold when it is unknown, such as the sale of pregnant animals, for example.
Therefore, the price must be known. All right.

forbade the type of sale which involves risk (or uncertainty)
