The ruling on what happens when there is an increase in the description of the item specified in the contract
Machine translationRead the Arabic original
The questioner : Yes. Yes. What? What do you mean? An increase. Yes, yes. What? What is required? Come on. Accepting it, and how is the increase in the afternoon prayer?
The Shaykh : Yes, yes, this means an increase in the description beyond what was agreed upon in the contract. But there is no disagreement regarding the descriptions; the descriptions are the same. A yellow, red, or black cow is the same. But the condition was that it yields a sa' (a dry measure of about 3 kg) of milk, and it turned out to yield a sa'. What is the ruling? If he wishes, the one who brought it may say, "If you wish, give me the sa' that is in excess."
