Musnad Ahmad 32:818

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Thabit, who said: I heard Anas ibn Malik saying: While the Messenger of Allah (may Allah bless him and grant him peace) was traveling, and a singer was singing for his wives, the Messenger of Allah (may Allah bless him and grant him peace) laughed. Then, he moved aside with them. He said: "O Anjashah, woe to you, be gentle with the glass vessels."
