Sayyiduna Sawadah bin al-Rabi' al-Jarmi (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) ordered that I be given a few camels (as a gift), and said: "Keep horses, for goodness is tied to the forelocks of horses until the Day of Resurrection."
