CHAPTER: THE VALIDITY OF THE HAJJ PERFORMED BY A BOY AND REWARD FOR ONE WHO ENABLES HIM TO PERFORM IT (BY ACCOMPANYING HIM AND BEARING EXPENSES FOR HIM)
Ibn Abbas reported that Allaah's Prophet (sallAllaahu alayhi wa sallam) met some riders at al-Rauha and asked who they were. They replied that they were Muslims. They said: Who art thou? He said: (I am) Messengef of Allaah. A woman (then) lifted up a boy to him and said: Would this child be credited with having performed the Hajj? Thereupon he said: Yes, and you will have a reward.
Ibn Abbas (Allaah be pleased with them) reported: A woman lifted up her child and said: Messenger of Allaah, would the child be credited with having performed the Hajj? Thereupon he said: Yes, and there would be a reward for you.
Karaib reported: A woman lifted a child and said: Messenger of Allaah, would he be credited with Hajj? He said: Yes. and for you there would be a reward.
A hadith like this has been narrated on the authority of Ibn 'Abbas through another chain of transmitters.
