Sa'id bin al-Musayyab (may Allah have mercy on him) says that a woman, or a man, freed six slaves, and had no wealth besides them. The Prophet (peace and blessings be upon him) was informed of it, and he (peace and blessings be upon him) drew lots between them and freed a third of them.
Imam al-Shafi'i (may Allah have mercy on him) said: They were freed during the illness in which the owner died.
