Sayyida Aisha Siddiqa (may Allah be pleased with her) narrates: The Prophet Muhammad (peace and blessings be upon him) raced with me and I outran him. After some time, when my body became heavier, the Prophet Muhammad (peace and blessings be upon him) raced with me again and he outran me. So the Prophet Muhammad (peace and blessings be upon him) said: "This is in return for that."
