Musannaf Ibn Abi Shaybah 32960 — How much of his wealth a man may

Amir bin Sa'd reported that Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) said: Once I became so ill that I was close to death. The Prophet (peace and blessings be upon him) came to visit me, and I said: "O Messenger of Allah (peace and blessings be upon him)! I have a great deal of wealth, and I have no heir except one daughter. May I give two-thirds of my wealth in charity?" He said: "No!" I said: "Then may I give half of my wealth in charity?" He said: "No!" I said: "And one third?" He said: "One third, and one third is a lot."
