The Prophet ﷺ had a camel-driver named Anjashah who had a beautiful voice. The Prophet ﷺ said to him, "Easy, Anjashah, do not break the glass vessels."Qatada explained that this referred to the delicate women.
كان للنبي ﷺ حاد، يقال له: أنجشة، وكان حسن الصوت، فقال له النبي ﷺ: رويدك يا أنجشة، لا تكسر القوارير. قال قتادة: يعني ضعفة النساء.
Bukhari narrated it in Adab (6011), and Muslim in Fadail (2323, 73), both through the route of Hammam, from Qatada, from Anas, who related it.His saying, "Anjasha" is with a fatha on the hamza, a saakin nun, and a jeem. He was a black slave who had a beautiful voice for camel-driving songs. Baladhuri said he was Abyssinian and was known by the kunya Abu Mariyah.In the Musnad of Abu Dawud Tayalisi (2161), from Anas bin Malik, who said, Anjasha used to sing camel-driving songs for the women, while Bara bin Malik used to sing them for the men. Anjasha had a beautiful voice, and whenever he sang, the camels would quicken their pace. So the Messenger of Allah ﷺ said, "Woe to you, Anjasha, go easy, drive your glass vessels gently."The Prophet ﷺ called the women "glass vessels" because of the weakness of their resolve, likening them to glass vessels because of their fragility. This is because when camels hear the driving-song, they quicken their walk, which jolts the rider and tires her out. So he forbade him from doing that, fearing it might harm the women or cause them to fall.
