It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Whoever buys a goat whose milk has been held back in its udder to make it appear a heavy milker, and then milks it for three days, has the choice: if he wishes he may keep it, and if he wishes he may return it along with a sa' of dates."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Asim except Dawud bin Isa, and Suwayd bin Abd al-Aziz is alone in narrating it."
