Sayyiduna Abu Huraira (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "Whoever buys a she-camel or a goat whose udders have been tied up (to accumulate milk), and then he milks it, he has the right to choose between two options: if he wishes, he may keep it, and if he wishes, he may return it and give along with it a container full of grain." ‘Awf narrated: This is when there is a deficiency in its milk. Hasan (may Allah have mercy on him) narrated that the Messenger of Allah (peace and blessings be upon him) said the same.
