Muhammad ibn Ahmad ibn Yahya narrated from Muhammad ibn Isa from Muhammad ibn Sinan from Ammar ibn Marwan from Sama'ah ibn Mehran from Abu Abdullah عليه السلام, regarding the saying of Allah سبحانه وتعالى, the Almighty and Glorious: "The will is for the parents and close relatives in a fair manner; it is an obligation upon the righteous" (Surah Al-Baqarah 2:180). Imam عليه السلام said: "This is something that Allah سبحانه وتعالى, the Almighty and Glorious, has designated for the one who holds this matter (referring to the rightful authority)." I asked: "Is there a set limit for this?" Imam عليه السلام replied: "Yes." I asked: "What is it?" Imam عليه السلام said: "The minimum is one-third of one-third."
