Sayyiduna Dhirar bin Azwar (may Allah be pleased with him) says: We presented a milch she-camel to the Messenger of Allah (peace and blessings be upon him) as a gift. In another narration, it is stated: Some members of my family sent me with milch she-camels to the Noble Prophet (peace and blessings be upon him). He (peace and blessings be upon him) instructed me to milk them, so I milked them. When I tried, with effort, to extract all the milk, the Prophet (peace and blessings be upon him) said: Do not do it like this; rather, leave the milk that causes (more) milk to be produced (in the udders).
