Is it permissible for a person to take the excess if the owner of the goods says, “Its value is such-and-such, and whatever is more is yours”?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on one who takes goods from the shop owner that are worth 1,000 riyals to him? Yes, what is the ruling on one who takes goods from the shop owner that are worth 1,000 riyals to him, and the owner says, “Whatever is more than the thousand is yours,” so he takes them to the market, and he is entrusted with them on the condition that if he does not sell them, he returns them to the shop owner again.

Answer:
If he gives you goods to sell in the market and sets their value, saying that whatever is more than that is yours, there is nothing wrong with that, because he has permitted it, and because this is in return for his effort, so there is nothing wrong with that.
