Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said:“Whoever buys a Musarrat (an animal whose milk has been retained in its udders), he has the option for three days; if he wishes to return it, he may return it along with a sa’ of grain, but not wheat.”Abu ‘Amir said:“It should not be wheat.”
