The Messenger of Allah ﷺ was on a journey, and with him was a black servant called Anjasha who was driving the camels with song. The Messenger of Allah ﷺ said, "Easy now, Anjasha. Go gently with the glass vessels. Be gentle with the glass vessels."In Abu Qilaba's version of the hadith, he explained that "the glass vessels" meant the women.
حدثنا يونس حدثنا حماد يعني ابن زيد عن ثابت
