(3) باب الْوَصِيَّةِ بِالثُّلُثِ
It was narrated from Muhammad bin Sa'd, from his father Sa'd bin Malik, that the Prophet came to him when he was sick and he said:
"I do not have any children apart from one daughter. Shall I bequeath all my wealth?" The Prophet said: "No." He said: "Shall I bequeath half of it?" The Prophet said: "No." He said: "Shall I bequeath one-third of it?" He said: "One-third, and one-third is much or large."
