Musnad Ahmad Hadith 9456

It is narrated from Abu Huraira (may Allah be pleased with him) in a marfu’ form that: Do not tie the udders of a goat or a she-camel in order to sell it at a good price. Whoever (being deceived by this) buys such a she-camel or goat, then he has the choice of two things, whichever is better for him: either he keeps the animal with himself (and lets the matter go), or he returns the animal to its owner and gives a sa’ of dates along with it. And do not make deals with traders outside (the market). And no woman should demand the divorce of her sister. And do not deceive one another, and do not sell over the sale of one another, and no townsman should sell the merchandise of a villager.
