Sayyiduna Sawadah bin al-Rabi' narrates: I came to the Prophet (peace and blessings be upon him) and asked him (peace and blessings be upon him) for something, and he (peace and blessings be upon him) ordered that I be given some camels. Then he said to me: "When you return home, instruct your people to take good care of the feeding of their young camels, and also tell them to keep their nails trimmed, so that they do not injure the udders of their animals with those nails while milking."
Imam Ahmad recorded it, and its chain is jayyid (good).
