question #3 Sahih al-Bukhari 2151, Book 34, Hadith 103 : How does Islamic law address buyer satisfaction in transactions involving livestock?

Allah’s Messenger (ﷺ) said, “Whoever buys a sheep which has been kept unmilked for a long period, and
milks it, can keep it if he is satisfied, and if he is not satisfied, he can return it, but he should pay one
Sa of dates for the milk.”
