It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that once he became ill, so the Prophet (peace and blessings of Allah be upon him) came to visit him. He said: O Messenger of Allah! Should I not bequeath all my wealth in the way of Allah? The Prophet (peace and blessings of Allah be upon him) said: “No.” He said: Should I bequeath half of my wealth? He said: “No.” He said: Should I bequeath one third of my wealth? He said: “Yes! Bequeath one third, and one third is also much.”
