Sayyiduna Nuqadah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to me: "O Nuqadah, find me a she-camel that gives milk and can also be ridden, and that has not given birth." The narrator says: I went and searched for one among the livestock, but I did not find any she-camel that was both a milker and docile (or one that could also be ridden). Then I found such a she-camel among the camels of a paternal cousin of mine. I brought her to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "O Nuqadah, leave the callers of the udder!" (The narrator is unsure; perhaps the words are:) "Leave the callers of the milk."
Al-Tabarani recorded it.
