Ismaili Ta'wil of al-Wasiyya — The Testament and Bequest: How the Prophet's Testament to 'Ali (the Wasiyya at Ghadir Khumm and at Death) Is Read in Ismaili Ta'wil as the Cosmological Chain Where Each Natiq (Prophetic Speaker) Leaves a Wasi (Executor/Successor) Who Holds the Batin While the Next Prophetic Cycle Awaits — Adam Left a Wasi, Noah Left a Wasi, Abraham Left a Wasi, Muhammad Left 'Ali — and Why the Wasiyya-Chain Is the Structure of Spiritual Continuity Between Prophetic Cycles

In Ismaili ta'wil, al-Wasiyya (الوَصِيَّة — The Testament, The Bequest, The Final Charge; from *w-s-y*: to charge, to bequeath, to instruct; awsa/yusi = to leave instructions, to make a bequest; wasiyya = the testament, the final instruction; wasi = the one who receives and executes the testament [executor]; in Islamic law: a wasiyya is a legally valid will or testament made by a person approaching death; it can transfer property, assign guardianship, or give instructions; in Islamic religious thought, the wasiyya has a deeper significance: every prophet leaves a wasiyya to his successor who will maintain the batin of the revelation while waiting for the next prophetic cycle; the Ghadir Khumm event [18 Dhul-Hijja, Year 10 AH / 632 CE]: on his return from the Farewell Pilgrimage, the Prophet halted at Ghadir Khumm and addressed the assembled Muslims; the hadith 'man kuntu mawlahu fa-'Ali mawlahu' [whoever I am his mawla, 'Ali is his mawla]; Shi'i tradition reads this as the public wasiyya establishing 'Ali as the Prophet's successor; Sunni tradition reads mawla in a sense of 'ally' or 'friend' rather than successor; the cosmological wasiyya in Ismaili thought: in Ismaili ta'wil, the wasiyya is not just a historical event at Ghadir Khumm — it is a cosmological structure that runs through all prophetic history: [1] Adam [Natiq] → his Wasi [the one who maintained batin after Adam]; [2] Noah [Natiq] → his Wasi; [3] Abraham [Natiq] → his Wasi [Ishmael or his son in different Ismaili formulations]; [4] Moses [Natiq] → his Wasi [Aaron/Joshua in different formulations]; [5] Jesus [Natiq] → his Wasi [Simon Peter in some Ismaili formulations, or Shi'i equivalents]; [6] Muhammad [Natiq] → 'Ali [Wasi] → chain of Imams; the structural logic: the Natiq establishes the zahir [the religious law of each prophetic era]; the Wasi and subsequent Imams maintain the batin [the inner meaning of the law] through the period between the Natiq's death and the next Natiq; the wasiyya is the mechanism of batin-transfer: the Natiq transmits the batin to the Wasi at the moment of the wasiyya, establishing the chain that maintains spiritual continuity; Ismaili ta'wil of al-wasiyya [specific Quranic texts]: [1] 2:180 'It is prescribed for you, when death approaches any of you and he leaves behind property, that he make a bequest [wasiyya] for parents and close relatives in a fitting manner': the zahiri wasiyya [bequest of property] points to the batin wasiyya [transmission of knowledge and walayah]; [2] the Quran's multiple references to the previous prophets' leaving of instructions for their communities: each prophet 'left instructions' [awsa] for what follows; in Ismaili ta'wil these instructions are wasiyyat of batin-knowledge; [3] the connection to nass: nass [explicit designation of the Imam's successor] is the ongoing mechanism of wasiyya within the Imamate; each Imam designates his successor by nass, transmitting the batin-knowledge of the wasiyya chain to the next Imam; the wasiyya and the mithaq: the primordial covenant [mithaq] established the structure of walayah; the wasiyya is the historical transmission mechanism through which the mithaq's structure is realized in each prophetic era; wasiyya connects the primordial past [mithaq] with the ongoing present [the Imam's nass]) is Ismaili ta'wil's account of spiritual continuity across prophetic cycles.
