صحيح البخاري

Narrated Anas:

The Prophet (ﷺ) was on a journey and a slave named Anjasha was chanting (singing) for the camels to let them go fast (while driving). The Prophet (ﷺ) said, "O Anjasha, drive slowly (the camels) with the glass vessels!" Abu Qilaba said, "By the glass vessels' he meant the women (riding the camels).
