The ruling on a lease without specifying the wage, relying on custom
Machine translationRead the Arabic original
Question:
Regarding the matter, the questioner says: It is customary that when I go to a race, I deal with him, and I say, "I will do such and such," then I tell him what he wants. If he says, "I want one hundred dinars," sometimes you give it to him, and sometimes he is cleverer, so he thinks, then he gives it to him.
Answer:
This is not valid. The lease must be known. If it is not established by a custom that regulates it, then it must be specified. So when you come to the plumber, you contract with him. You tell him, "You will do this plumbing work for such and such." You contract with him on the amount from the start, so that no dispute arises and no harm comes to either of you. Because this matter is not established by a custom that you can return to. Yes.
