Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: While the Messenger of Allah (peace and blessings be upon him) was travelling on the road to Makkah, a woman in her litter spoke to him (peace and blessings be upon him); she took hold of a child by the upper arm, lifted him up and said: O Messenger of Allah! Is there Hajj for him? He (peace and blessings be upon him) said: "There is Hajj for him, and you will have a reward."
