It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man came to the Messenger of Allah (peace and blessings be upon him) and said: "My father is very old; he reached Islam but has not been able to perform Hajj. He cannot even stay steady on a mount, and if I tie him to the mount with a rope, I fear he may die." So the Messenger of Allah (peace and blessings be upon him) said: "Perform Hajj on behalf of your father." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with these words.

It is narrated from Sayyiduna Abu Razin (may Allah be pleased with him) that he said: "O Messenger of Allah! My father is very old; he has no strength for Hajj, nor for Umrah, nor for travel." So he (peace and blessings be upon him) said: "Perform Hajj and Umrah on behalf of your father." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
