Mukhtasar Muslim (Abridged) 928 — Prohibition of musarrat sale

Narrated from Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: Whoever buys a goat whose udder is full of milk has the option for three days; if he wishes, he may keep it, or if he wishes, he may return it, and along with it, he should give one sa’ of dates.
