Abu Salamah narrates from Sayyidah Aishah (may Allah be pleased with her) that she was with the Prophet (peace and blessings be upon him) on a journey and they raced, and I won. When my body had become heavy, we raced again and the Prophet (peace and blessings be upon him) won. He (peace and blessings be upon him) said: "This is in return for the first race."
