Hazrat Anas bin Malik (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) was on a journey and with him was his Abyssinian slave, whose name was Anjasha. He was reciting poetry (which caused the riding animals to move quickly). The Noble Messenger (peace and blessings be upon him) said, "Alas (Woe to you), O Anjasha! Drive slowly with the glass vessels." (By "glass vessels" he meant women, because they too are delicate like glass.)
