question #1 Sahih al-Bukhari 2164, Book 34, Hadith 115 : What is the ruling on returning an animal that has been kept unmilked for a long time in Islamic jurisprudence?

Whoever buys an animal which has been kept unmilked for a long time, could return it, but has to pay
a Sa of dates along with it. And the Prophet (ﷺ) forbade meeting the owners of goods on the way away
from the market.
