Qutaybah ibn Sa'id narrated to us, Ya'qub — meaning Ibn 'Abd al-Rahman al-Qari — narrated to us, from Suhayl, from his father, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever buys a sheep that has been left unmilked (musarrah) has the choice regarding it for three days: if he wishes, he may keep it, and if he wishes, he may return it, and return with it a sa' of dates."
