H 757, Ch. 64, h 1

Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus and Ali ibn Muhammad from Sahl ibn Ziyad, abu Sa‘id from Muhammad ibn ‘Isa from Yunus from ibn Muskan from abu Basir who has said that

he asked abu ‘Abdallah (a.s.) about the following words of Allah, the Most Holy, the Most High. “Believers, obey God, His Messenger, and your leaders (who possess Divine authority). . . .” (4:59) The Imam (a.s.) said, “This was sent from heavens about Ali ibn abu talib al-Hassan and al-Husayn (a.s.).”

I then said, “People say, “Why did He not specify Ali and his family by their names in the book of Allah, the Most Holy, the Most High?’”

The Imam (a.s.) said, “Say to them, ‘The command for prayer came to the Messenger of Allah but He has not specified (the number of the Rak‘ats) for them three nor four. It, in fact, was the Messenger of Allah who explained to them this matter. The command for Zakat (a form of income tax) came to the Messenger of Allah and there was no specific taxable number such as one Dirham on every forty Dirham. It was the Messenger of Allah who explained it for them. The command for Hajj came to the Messenger of Allah. It did not say walk senven times around the Ka‘ba . It was the Messenger of Allah who explained it for them. The verse about obedience came “Believers, obey God, His Messenger, and your leaders (who possess Divine authority). . . .” (4:59) It came to declare that Ali, al-Hassan and al-Husayn (a.s.) were the leards who possessed Divine authority. The Messenger of Allah then said about Ali (a.s.), “On whoever I have Divine Authority, then Ali (a.s.) has Divne Authority over him also.” He also has said, “I enjoin you to follow the book of Allah and my family because have prayed to Allah, the Most Holy, the Most High not to separate these two from eachother until He will make them arrive al-Kawthar (at the pool of Paradise) to meet me. He has granted my prayer as such.” The Holy Prophet (s.a.) has said, “Do not try to teach them (The Imam (a.s.) becaue they are far more knowledgeable than you.” The Holy Prophet (s.a.) has said, “The Imam (a.s.) will never take you out of the gate of guidance and they never make you enter the gate of misguidance.” Had the Messenger of Allah remained silent and would not explain anything about his Ahl al-Bayt (family) the family of so and so would have advanced their claim for Imamat (Leadership with Divine Authority). However, Allah, the Most Holy, the Most High, has revealed it in His book to confirm the explanantions of His Prophet about Ahl al-Bayt (in the following verse), “People of the house, God wants to remove all kinds of uncleanliness from you and to purify you thoroughly.” (33:33) Ali, Fatima, al-Hassan andlhy (a.s.) were there and the Holy Prophet (s.a.) made them to enter under al-Kisa’ (the Cloack) in the house of ’Umm salama and then said, “O Lord, every prophet has a family and a gravity, and these are my family and gravity.” ’Umm Salama at this point said, “Am I not of your family?” The Holy Prophet (s.a.) said, “You are in goodness but these are my family and my gravity.” When the Messenger of Allah passed away Ali (a.s.) had the utmost priority and guardianship of the people all because of what the Messenger of Allah had preached about him. It was because of raising him up for the people and holding his hand in his hand. When Ali (a.s.) (was about to) passed away he could not (and would not) enter Muhammad ibn Ali or al-‘Abbass ibn Ali or anyone of his other sons in the position of Imamat. Otherewise, al-Hassan and al-Husayn (a.s.) would have said, “Allah, the Most Holy, the Most High, has revealed about us jus as He has done so about you, and He has commaned people to obey us just as He has commanded people to obey you. The Messenger of Allah has preached to people about us just as he has done so about you. Allah has removed al-Rijs uncleanliness from us just as He has done so to you. When Ali (a.s.) left this world, al-Hassan had the utmost priority for Imamat (Leadership with Divine Authority) because he was the eldest. When was about to die he could not, and would not, enter his sons in the position of Imamat.It is because ;Allah, the Most Holy, the Most High, says, “. . . The relatives are closer to each other, according to the Book of God, than the believers and the emigrants. . .” (33:6) He then places Imamat (Leadership with Divine Authority) in his sons. If so, al-Husayn (a.s.) would have said, “Allah has commanded people to obey me just as He has commanded people to obey you and to obey your father. The Messenger of Allah has preached to people about me just as he has preached to people about you and your father. Allah has removed al-Rijs (unleanliness) from me just as He has removed from you and your father. When the Imamat (Leadership with Divine Authority) was infull force with al-Husayn (a.s.) there was no one in his family to who could claim against him as he could calim against his brother and father, had they wanted to diver it from him and they would not do so. After them it found its place with al-Husayn (a.s.) and the interpretation of this verse continued, “. . . The relatives are closer to each other, according to the Book of God, than the believers and the emigrants. . . .” (33:6)

After al-Husayn (a.s.) Imamat (Leadership with Divine Authority) found its place with Ali ibn al-Husayn (a.s.). After Ali ibn al-Husayn (a.s.) it (Leadership with Divine Authority) found its place with Muhammad ibn Ali (a.s.).” The Imam (a.s.) said, “Al-Rijs means doubts, I swear by Allah that we never doubt in our Lord.”

Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Khalid and al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from Yahya ibn ‘Imran al-Halabi from Ayyub ibn al-Hurr and ‘Imran ibn Ali al-Halabi from abu ‘Abdallah (a.s.) a similar hadith.
