Book 25, Hadith 28

It was narrated from Ibn ‘Abbas that his brother Fadl was riding behind the Messenger of Allah (ﷺ) in the morning of sacrifice (i.e., the 10th of Dhul-Hijjah), when a woman from Khath’am came and said:“O Messenger of Allah, the command of Allah has come for His slaves to perform Hajj, but my father is an old man and cannot ride. May I perform Hajj on his behalf?” He said: “Yes, because if your father owed a debt you would pay it off.”
