Imam Muhammad Baqir (a.s.) informed: The pinnacle of the affair and its peak and its key and door to things and satisfaction of the All-Merciful is obedience to the Imam after his recognition. If a man stands in its nights and fasts during its days and gives in charity all his wealth and performs Hajj during his life and does not recognize the Mastership of Allah’s Guardian and does not befriend him and does not direct all his deeds towards him then Allah will not reward him for any action and he is not from the people of faith.
