Sahih al-Bukhari 6210

Sulayman ibn Harb narrated to us: Hammad narrated to us, from Thabit, from Anas; and Ayyub narrated to us, from Abu Qilabah, from Anas, may Allah be pleased with him, that the Prophet, peace and blessings be upon him, was traveling. A young man called Anjashah was singing to urge the camels along. The Prophet said, ‘Slow down, Anjashah; drive the crystal vessels gently.’ Abu Qilabah said: He meant the women.
