A man who settles with his slave on a set payment

Al-Hakam (may Allah have mercy on him) said: If a slave is one who pays a fixed share of the levy and he enters into a sale, that transaction is upon his own neck.

Hammad (may Allah have mercy on him) said: If his master has given him permission to sell, then it is upon his neck.

Al-Harith and Hammad (may Allah have mercy on them both) said: If a master agrees with his slave on a fixed levy, this amounts to giving him permission to sell.
