Musnad Abi Ya'la 6187 — the Messenger of Allah ﷺ forbade a man

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade a man from bargaining over his brother's bargain; he forbade false bidding (to raise the price); he forbade going out to meet merchandise coming from outside (before it reaches the market); he forbade a woman from asking for the divorce of her (religious) sister; he forbade withholding (surplus) water for fear that the pasture would be grazed (because of it); and he forbade a town-dweller from selling on behalf of a desert-dweller. And (he said): "Whoever gives someone a milk-giving animal as a gift (to benefit from its milk), that animal goes out in the morning carrying charity and returns in the evening carrying charity, both for its morning milk and for its evening milk."
