Infallibility As with the Islamic prophet Muhammad, the twelve imams are regarded as infallible in Twelver Shi'ism, that is, protected from sin and error through divine grace. The scope of this has been debated, but at least covers imams’ religious rulings and views. Infallibility () of imams, in their capacity as divinely-sanctioned leaders, is viewed as a logical necessity in Twelver Shi'ism lest the religion is corrupted, or people are led astray. This infallibility, however, is not viewed as inability to sin. Rather, the esoteric knowledge of prophets and imams, for instance, their vivid understanding of God's punishment, produces a faculty that prevents them from disobedience of God. That is, their infallibility is a byproduct of their divine knowledge. Verse 2:124 is one of the Quranic verses cited to support the infallibility of imams, in which all wrongdoers are excluded from imamate.
Best of men Each imam is the best of men () in his time, that is, most excellent among them in religious qualities, for otherwise, it is argued, God would have appointed someone else as the imam. Similarly, it is argued that imams must be foremost in observing the religious values that they preach. Imamate is ranked even higher than prophethood in Twelver Shi'ism, citing the Quranic story in verse 2:124, where Abraham is promoted to imamate when he is already a prophet. In particular, there is total consensus that the twelve imams are the most superior amongst humans born on Earth following Muhammad's birth, with some saying that they even exceed some or even all prophets except Muhammad himself. This is often justified because Muhammad inherited the total knowledge of all prophets, and the twelve imams in turn inherited Muhammad's superior knowledge, although, historically there have been disagreements on the twelve imams ranking in contrast to the other prophets with a cohort even believing that the twelve imams do not exceed any prophet at all. Amongst the twelve imams themselves, some are believed to have been equal in knowledge, although some of them, like Ali ibn Abi Talib (and Hassan and Hussain to a lesser extent), may have been superior to the rest in rank. This also implied that every new piece of divine knowledge was presented first to the imam's predecessors and then to him. Generally, prophecy and imamate may be joined in a person. That is, virtually all known (i.e. named) prophets in Islam, including Muhammad, were also imams in that they too possessed the esoteric knowledge of religion as well as brought new revelations. Yet not every imam was a prophet for some imams did not bring new divine revelation, but rather simply executed it such as
Simon Peter, the successor of
Jesus.
Most beautiful names of God In Twelver doctrine, Muhammad and the twelve imams are regarded as the highest manifestations of the most beautiful names of God (), which are the qualities that describe the knowable God, that is, those descriptions of God which are manifested in his creation. For instance, God is indulgent () and vengeful (), satisfied () and angry (). Imams are thus the best representatives of God's attributes; they are His image and face; the perfect human beings (). In particular, knowing imams is equivalent to knowing (the knowable) God, which is in turn the ultimate goal of the creation. It is in this sense that the imam is said to be the Proof of God (), the Vicar of God (), and the Threshold of God (). In particular, as the divinely-sanctioned guide, imam is the highest proof () of God on Earth and His evidence on the
judgement day against those who deny or disobey Him.
Light of God The fourteen infallibles are said to have been a primordial light that became the cause and instrument for the rest of the creation. This so-called Muahammadan light was carried through the line of prophets, beginning with
Adam, until it became embodied in the fourteen infallibles. Through this divine light the imams illuminate the hearts of believers, guiding them toward God. This divine light is also said to be responsible for the infallibility of imams.
Intercession It is believed that the fourteen infallibles will intercede for the Muslim community in the hereafter, through which their sins will be overlooked or they will reach a higher spiritual status. It is the Shia community, however, that will especially benefit from this intercession (). Just as the imams, particularly Husayn, patiently endured suffering, privation, rejection and persecution on Earth, they will be exalted and vindicated by God in the hereafter, sharing in His sovereignty over the creation through intercession, a prerogative which they will share with their true followers, who had in turn suffered for imams’ sake. Yet this absolutist perspective has been curtailed by emphasizing that intercession is only accessible to the virtous and pious. ====== The word and its cognate can mean 'Lord', 'master', 'trustee', 'guardian', 'helper', 'protecting friend', 'freed slave', and (spiritual or material) 'heir'. First, () signifies the nearness of imam to God, who reveals to him His secrets, and grants him authority over His creation. Second, imam and is the supreme spiritual guide, and the exclusive religio-political authority after Muhammad. == to imams==
