Abdullah bin Abbas reported,

The Prophet ﷺ was at al-Rawha when he met a group of riders and greeted them.He asked, "Who are the people?"They replied, "We are Muslims. And who are you?"He said, "The Messenger of Allah ﷺ."A woman was startled, so she took hold of a young boy by his arm and lifted him out of her litter and asked, "Messenger of Allah, does this child have a valid Hajj?"He replied, "Yes, and you will have a reward."
