From Sahih Muslim (Hadith 6039):
Anas reported that Allah's Apostle (ﷺ) came to his wives as the camel-driver who was called Anjasha had been, driving (the camels) on which (they were riding). Thereupon he said:Anjasha, be careful, drive slowly for you are driving the mounts who carry vessels of glass. Abu Qilaba said that Allah's Messenger (ﷺ) uttered words which if someone had uttered amongst you, you would have found fault with him
