Musnad Ahmad 25:751

Nuh ibn Maymun narrated to us, he said: Abdullah—meaning al-Umari—informed us, from Muhammad ibn Uqbah, from his brother Ibrahim ibn Uqbah, from Kurayb, from Ibn Abbas, that a woman brought out a young boy of hers and said: "O Messenger of Allah, is there a Hajj for this one?" He said: "Yes, and you have a reward."
