1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ’Isa from al-Hasan ibn Mahbub who has said, "I asked abu al-Hassan al-Rida عليه السلام about the saying of Allah, the Most Majestic and Most Exalted: “We have chosen heirs for every legacy that parents and relatives may leave. Let those who have been promised a bequest receive their share of the legacy. . .”" (4:33) He عليه السلام said: It is a reference to the Imams (peace be upon them). Through them, Allah, the Most Majestic and Most Exalted, has established your covenants.”
