Chapter: Validity of a child's hajj, and the reward of the one who takes him for Hajj
Ibn Abbas reported that Allah's Apostle ( صلی اللہ علیہ وسلم ) 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 Allah. 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 (Allah be pleased with them) reported: A woman lifted up her child and said: Messenger of Allah, 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 Allah, 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.
