Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) was traveling, and with him was a black slave whose name was Anjasha. He was reciting poetry to urge the camels on. The Prophet Muhammad (peace and blessings be upon him) said to him: "O Anjasha, go gently, you are carrying glass vessels." The Prophet Muhammad (peace and blessings be upon him) meant that he was carrying women.
