Sayyiduna Nuqadah al-Asadi (may Allah be pleased with him) narrates: (Someone from my people) sent me with a milch she-camel to the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) said to me: "Milk her." So I milked her, and he (peace and blessings be upon him) said: "O Nuqadah, leave what calls the milk." (That is, leave some milk in the udder so that it draws down more milk.) So I left her teats full and did not squeeze out all the milk.
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Nuqadah (may Allah be pleased with him) only through this chain; Ishaq bin Muhammad al-Farwi is alone in narrating it."
