The matters that Allah, the Most Holy, the Most High, and His Messenger صلى الله عليه وعلى آله وسلم have sanctioned as obligatory of the beings with the Imams عليه السلام

6. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Musa ibn Sa‘dan from ‘Abdallah ibn al-Qasim from ’Abd al-Qahhar from Jabir al-Ju‘fi from abu Ja’far ( a.s.) who has said that the Messenger of Allah has said the following. “Whoever would like to live as I have lived and die as will do and enter the garden that my Lord has promised to me and hold in hands the stick that Allah has planted with His own hands he then must love and acknowledge (Leadership with Divine Authority of) Ali عليه السلام and his successors after him because they do not lead you into the gates of misguidance or take you out the gate of true guidance. Thus, do not try to teach them because they know more then you do. I have asked my Lord not to cause any separation between them and the Holy Quran until the time they will arrive in my presence near the al-Kawthar in paradise like this (showing his two fingers stretched side by side). The pond of al-Kawthar which is as big as from San‘a’ to ’Ayla (a place between Makka and Madina) with cups of gold and silver around it as many as the stars.
