It was narrated from Ishaq bin Ibrahim, from his grandfather Umair, who was the freed slave of Ibn Masud, that Abdullah said to him: "O "Umair, I have set you free in a good way. I heard the Messenger of Allah ﷺ say: Any man who frees a slave and does not say anything about his(the slave’s) wealth, it belongs to him (the slave) ‘So tell me, how much wealth do you have?”’
