Hadith 441
Sayyiduna Ibn Abbas (may Allah be pleased with them) narrates: A man came to the Messenger of Allah (peace and blessings be upon him) and said: My father is old and cannot perform Hajj; can I perform Hajj on his behalf? The Prophet (peace and blessings be upon him) said: "If your father had a debt, would you pay it off for him?" He replied: Yes! The Prophet (peace and blessings be upon him) said: "Then Allah's debt is more deserving of being paid. Perform Hajj on his behalf."
