Indeed...
Indeed, they both are Imams after their father, Ali, and I am their father prior to him—Thus say: “We obey Allah, and obey you, Ali, al-Hasan, al-Husain, and the Imams that you mentioned, based on the covenant and the pledge that are taken from us for the Commander of the Believers, from our hearts, our souls, our tongues, and through handshaking for him who can reach his hand to them both (the Prophet (PBUH&HF) and Imam Ali (PBUH)), or else through affirming by tongue.
We shall not seek any substitute for it, nor shall we ever let our souls deviate from it.” You are also witness over us; so are anyone who obeyed, visible or covered, Allah’s Angels, His forces, and His servants. And Allah is greater than every witness.” O people! What do you say?
Verily, Allah is well-aware of every voice and the secrecy of every soul; “He who accepts guidance, it is to the benefit of his own soul, and he who goes astray, does so to his own loss.”1 Those who pledge fealty, they indeed pledge fealty to Allah; the hand of Allah is over their hands.2 1 Chapter 39, Verse 41 of the Holy Quran. 2 cf. Chapter 48, Verse 10 of the Holy Quran. O people!
Be mindful of Allah, give your oath of allegiance to Ali, the Commander of the Believers, may Allah’s blessings be upon him, to al-Hasan and al-Husain, and to the Imams [from them]. a goodly Word, that is enduring.1 Allah shall cause whoever acts treacherously to perish and shall have mercy on whoever remains loyal.
“Thus, anyone who violates his oath has indeed violated his (own) soul, and anyone who fulfills the covenant he has made with Allah, He shall soon grant him a great reward.”2 1 This phrase refers to the Verse 28, Chapter 43 of the Holy Quran, where Allah states, “(Allah) made it a Word, enduring in his posterity…” On the commentary of this verse, Imam al-Sadiq (PBUH) said, “This (word) means leadership (Imamate), which Allah has placed it in the offspring of al-Husain (PBUH) until the Day of Judgement.” (Kamal al-Din, p.
358, Hadith 57; Bihar al-Anwar, vol. 24, p. 177, Hadith 8). 2 Chapter 48, Verse 10 of the Holy Quran. O people! Say what I told you, and greet Ali with the title of “The Commander of the Believers.” And also say: “We listened, and obeyed, Your forgiveness (do we seek), Our Lord, and towards Your (reward or punishment) is the eventual turn.”1 And say: “Praise be to Allah who has guided us to this. Never could we be guided had Allah not guided us.”2 1 Chapter 2, Verse 285 of the Holy Quran.
