Sayyiduna Fadl bin Abbas or Sayyiduna Ubaidullah bin Abbas (may Allah be pleased with them) narrated that a man said, "O Messenger of Allah! My mother or father is old; if I make them ride (for Hajj), they will not be able to sit properly, and if I tie them to the mount, I fear they may die." The Prophet (peace and blessings be upon him) said, "What do you think, if your father or mother had a debt, would you pay off their debt?" He replied, "Yes, I would certainly pay it off." The Prophet said, "Then perform Hajj on behalf of your father or mother."
