4. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from Ahmad ibn Muhammad ibn ‘Abdallah from al-Hassan from Ibn Abi ‘Umayr from Muhammad ibn Ishaq ibn ‘Ammar who has said the following
“I said to Abu al-Hassan the 1st (a.s.) 'Would you guide me to a person from whom I could learn my religion?'” He (the Imam) said, “This is my son Ali. My father took my hand until we were at the grave of the Messenger of Allah (s.a.w) and said, “My son, Allah, the Most Holy, the Most High, has said, “. . I am appointing someone as my deputy on earth,. .” (2:30) When Allah, the Most Holy, the Most High, says a word He keeps His word.”
