Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: Abul Qasim (peace be upon him) said: "Whoever buys a musarriya (an animal whose milk has been withheld), he has the option; if he wishes, he may keep it, and if he wishes, he may return it along with one sa’ of dates, but (he should give) dates, not wheat."
