Sayyidah Asma bint Abi Bakr (may Allah be pleased with her) said: "I used to serve al-Zubayr (may Allah be pleased with him). He had a horse, and I used to look after it, and no work in the service was harder on me than looking after the horse. I would cut grass for it and tend to it. Then I got a maidservant: some captives came to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) gave me a maidservant. She relieved me of looking after the horse and lifted its burden from me."
