Musnad Ahmad 32:1698

'Affan and Bahz narrated to us, they said: Hammam narrated to us, he said: Qatadah informed us, from Anas ibn Malik, that a camel driver for the Prophet, may Allah bless him and grant him peace, was called Anjashah. He said: And he had a beautiful voice. He said: So the Prophet, may Allah bless him and grant him peace, said: "Gently, O Anjashah, do not break the glass vessels." Qatadah said: Meaning the weak ones among the women.
