"The Messenger of Allah said: 'If any one of you sells a sheep or a milch- camel, let him not refrain from milking it.'' (Sahih )
Sunan an-Nasa'i Book 44, Hadith 38
← Previous Hadith there was a man whose mental faculties were lacking, and he used to buy and sell. His family came to the Prophet and said: "O Prophet of Allah stop him." So the Prophet of Allah called him, and told him not to do that. He said: "O Prophet of Allah, I cannot bear to be away from business," He said "If you engaged in a deal then say: 'There is no intention to deceive. "' (Sahih )

Sunan an-Nasa'i Book 44, Hadith 37 Next Hadith → "Do not go out to meet the riders, and do not bind the udders of camels and seep. Whoever has boughty anything in that manner has two choices: If he whishes he may keep it, or if he wants to return it he may return it, along with a Sa of dates." (Sahih )
