“One day I was with Imam Abu Ja’far Muhammad bin Ali al-Baqir (as). When the all left, he said to me: “O Abu Hamza, what is inevitable and that Allah will not change is the advent of the last imam of ours; al-Mahdi. Whoever doubts this matter, will be unbeliever before Allah. I swear that his name will be like mine and his surname will be like mine. He will be the seventh after me. He will fill the world with justice and equity after it has been filled with injustice and oppression. O Abu Hamza, he, who will attend his (Imam al-Mahdi’s) appearance and will not submit to him, has not submitted to Muhammad and Ali (peace be upon them) and then he will be forbidden from being in Paradise, his abode will be the fire, and evil is the abode of the unjust!” Clearer than this is the saying of Allah: “Surely the number of months with Allah is twelve months in Allah’s ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right religion; therefore be not unjust to yourselves regarding them.” Knowing the months is not to be considered as the right religion because the Jews, the Christians, the Magi and all peoples know the number and the names of the months. They are but the twelve imams, who are the guardians of the religion. Among the four sacred ones is Imam Ali (as), whose name Allah has derived from His name as He has derived the name of the Prophet (S). Three other imams have the name Ali. They are Ali bin al-Husayn, Ali bin Musa and Ali bin Muhammad. So this name (Ali), which has been derived from one of the attributes of Allah, has deserved to be sacred. Peace and blessing be upon Muhammad and his progeny, the pure, the sacred.
