How the Shi’ah Arrived at the Infallibility of the Imamate

بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ

The word, “Shi’ah” lexically means, “adherent,” even “answar”, such that the related word, “tashayyu’”, “partisanship,” denotes “al-intiswar”, “the victory of one over another”.  Historically, the word, “Shi’ah” refers to the supporters of Sayyidina ‘Ali ibn Abu Thalib (k.w.).  The term refers to the explicit conviction that the right to the caliphate fell only to Sayyidina ‘Ali (k.w.) and his children.  They differed amongst themselves, thereafter, as to which among his descendants had priority: the Zaydiyyah asserted the imamiyyah through the third-generation descendent, Imam Zayd ibn ‘Ali ibn al-Husayn (q.s.); the Isma’iliyyah asserted the imamiyyah through the seventh-generation descendent, Imam Isma’il ibn Ja’far asw-Swadiq (q.s.) and the Itsna ‘Ashari, Twelver Shi’ah, asserted the imamiyyah through Imam Muhammad ibn al-Hasan al-‘Askari (q.s.).

The Twelver Shi’ah hold that the authority of the Imamate is one of the fundamental principles of religion that do not admit rational interpretation and, therefore, is not subject to ijtihad, independent judgement.  Nor are ancillary matters related to it subject to such independent judgement, although they may admit rational interpretation.  That is, choosing the imam, leader, is not achieved by election through the bay’ah, pledged allegiance, of the community, as the Ahl as-Sunnah wa al-Jama’ah hold, but rather through Divine Appointment and textual designation, from proof-texts drawn from the Qur’an and sunnah.  The pledged allegiance is subsequent to, and dependent on, this Divine Appointment.  The Shi’ah narrate various textual proofs for this position, among them the hadits of the pond of Khumm: “Whosoever I am his master, so too ‘Ali is his master.”  Likewise, they advance rational proofs, including that the orthodox community, being comprised merely of a multitude of fallible individuals, is not immune from mistakes, and that mistakes in this matter of choosing the leader yield nothing less than chaos and social disintegration.  For these reasons, among others, this matter must be effected through Divine Appointment, and thereby secured against the fallibility of the populace. 

Given that they were Divinely Appointed, the a’immah are understood to be Protected from error.  Shi’iah adduce both textual and rational proofs for this doctrine, including respectively Allah’s (s.w.t.) Address to Abraham (a.s.): 

سُوۡرَةُ البَقَرَة

۞ وَإِذِ ٱبۡتَلَىٰٓ إِبۡرَٲهِـۧمَ رَبُّهُ ۥ بِكَلِمَـٰتٍ۬ فَأَتَمَّهُنَّ‌ۖ قَالَ إِنِّى جَاعِلُكَ لِلنَّاسِ إِمَامً۬ا‌ۖ قَالَ وَمِن ذُرِّيَّتِى‌ۖ قَالَ لَا يَنَالُ عَهۡدِى ٱلظَّـٰلِمِينَ (١٢٤)

And remember that Abraham was Tried by his Lord with certain Commands, which he fulfilled; He Said, “I will Make you an imam to the nations.”  He pleaded, “And also (a’immah) from my offspring!”  He Answered, “But My Promise is not within the reach of evil-doers.” (Surah al-Baqarah:124) 

Allah (s.w.t.) is Very Clear that His Covenant does not include wrongdoers and the argument that the infallibility of the a’immah interrupts the infinite regress of moral culpability that otherwise obtains.
