Ismaili Ta'wil of al-Nass — Explicit Designation: How the Ismaili Doctrine of Nass (the Imam's Explicit Appointment of His Successor by the Previous Imam Through Divine Command) Is Rooted in Quranic Verses Including 5:67 (Ghadir Khumm) and How Nass Distinguishes the Imamate from All Other Forms of Political and Religious Succession

In Ismaili doctrine and ta'wil, al-Nass (النَّصّ — Explicit Designation, explicit text; from *n-s-s*: to specify explicitly, to designate clearly; the doctrine: the Imam's successor is not elected, selected by consultation, or inherited through biological priority alone — the Imam explicitly designates his successor by divine command [nass]; this nass is binding on the community; the Quranic basis: [1] 5:67 'O Messenger, convey what has been revealed to you from your Lord. If you do not, then you have not conveyed His message. God will protect you from the people'; the event of Ghadir Khumm: on the 18th of Dhu al-Hijja, 10 AH / 632 CE, the Prophet returned from his final hajj; at a pool [ghadir] called Khumm between Mecca and Medina, he delivered a sermon; the key statement: 'Whoever considers me their mawla [master/leader], then 'Ali is their mawla'; Shi'i interpretation: this was the explicit designation [nass] of 'Ali as the Prophet's successor; Sunni interpretation: mawla means 'friend' or 'supporter' — not 'political/religious leader'; the Ismaili reading: Ghadir Khumm is the paradigmatic nass event — the Prophet, by divine command [5:67 'convey what has been revealed to you'], designated 'Ali explicitly; to not convey this would have been a failure of prophetic mission; the verse's urgency ['if you do not, then you have not conveyed His message'] indicates that this particular designation was a central part of the prophetic mission, not a minor addition; [2] 33:33 ['God only intends to remove evil from you, O People of the Household, and to purify you with thorough purification'] — the ahl al-bayt verse; in Ismaili ta'wil, the tahara [purification] of the ahl al-bayt is the qualification that makes the Imam's nass authoritative; only a purified Imam can designate a qualified successor; [3] 4:59 'Obey God and obey the Messenger and those in authority among you' — uli al-amr as the Imams; the requirement of obedience to uli al-amr is grounded in the Imam's nass; nass vs shura [consultation]: the caliphate after the Prophet was determined by consultation [Abu Bakr selected at the Saqifa], then designation [Abu Bakr designated 'Umar], then a consultative committee ['Uthman selected by the shura], then the community's bay'ah to 'Ali; Ismaili ta'wil: these selection mechanisms, however historically significant, do not constitute nass; nass requires divine command through the Imam, not human deliberation; the chain of nass: 'Ali designated al-Hasan; al-Hasan designated al-Husayn; al-Husayn designated his son; the chain continues through each Imam to the present; any break in the nass chain would end the legitimate Imamate; nass as the structural guarantee: because each Imam receives divine guidance and designates through divine command, the ta'wil transmission is guaranteed to continue without error; a human-selected leader might err; a divinely-designated Imam cannot; nass as the foundation of walayah: the entire edifice of walayah and ta'wil rests on the validity of nass; if the designation is legitimate, the Imam's ta'wil is authoritative; if not, nothing that follows can be trusted) is the Ismaili constitutional theology of legitimate succession.
