The obligation to obey the Imams (a.s.)

a man from Persia asked Imam abu al-Hassan (a.s.) “Is obedience to you obligatory?” The Imam (a.s.) replied, “Yes, it is obligatory.” The man then asked is in the same way as obedience to Amir al-Mu’minin Ali ibn abu Talib (a.s.)?” The Imam (a.s.) replied “Yes, it is obligatory in the same way,”

I asked Imam abu Ja‘far (a.s.) if I may state before him my religion and faith in Allah, the Most Holy, the Most High. The Imam (a.s.) said, “Say it and let us hear them.” I said, “I testify that there is no god other than Allah Who is One and has no partner. I testify that Muhammad (s.a.) is the servant and messenger of Allah. I acknowledge the truth of all that he has brought from Allah. I testify that Imam (a.s.) was the Imam obedience was and is obligatory by the command of Allah. After him Imam al-Hassan was the Imam obedience to whom was and is obligatory by the command of Allah. After him Imam al-Husayn was and is the Imam obedience to whom was and is obligatory by the command of Allah. After him Imam Ali ibn al-Husayn was and is the Imam obedience to whom is obligatory by the command of Allah. I continued until it was the turn for him and I said, “Then yourself, may Allah have you in His blessings are such Imam.” The Imam (a.s.) said, “This is the religion that belongs to Allah and it is the religion of His angels.”
