Musannaf Ibn Abi Shayba 25:122

Ibn ‘Ulayya narrated to us, from Ibn ‘Awn, from Anas ibn Sirin, that a woman bequeathed thirty dirhams in the way of Allah. When the time of the pilgrimage (al-tarfa) came, I said to Ibn ‘Umar, "A woman bequeathed thirty dirhams in the way of Allah, so shall we give it for the Hajj?" He said, "Indeed, it is from the way of Allah."
