It is narrated from Hazrat Anas (may Allah be pleased with him) that Hazrat Bara bin Malik (may Allah be pleased with him) used to chant the camel-driving songs for the men with the Prophet (peace and blessings be upon him), and Anjasha (may Allah be pleased with him) for the women. Anjasha had a very beautiful voice. When he started chanting, the camels began to run swiftly. Upon this, the Prophet (peace and blessings be upon him) said, "Anjasha! Drive gently with the glass vessels."
