Musannaf Ibn Abi Shaybah 35034 — What they said on a captive in enemy

Hisham (may Allah have mercy on him) says that al-Hasan (may Allah have mercy on him) said regarding a captive in the hands of the enemy: "If he gives someone a gift, or gives someone something of his own free will, and makes a bequest of a third of his wealth, it is valid."
