Musannaf Ibn Abi Shaybah 15543 — A child, a slave or a Bedouin

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he (peace and blessings be upon him) met some riders at al-Rawha' and asked: "Who are these people?" They said: "Muslims." Then they asked: "Who are you?" He (peace and blessings be upon him) said: "The Messenger of Allah (peace and blessings be upon him)." A woman lifted up her child and asked: "Does this one have a Hajj?" He (peace and blessings be upon him) said: "Yes, and you will have a reward."
