Question: What linguistic grouping includes the old version of the language used by Sarmad Kashani?

full_context: Document 1: Iranian languages: Two of the earliest dialectal divisions among Iranian indeed happen to not follow the later division into Western and Eastern blocks. These concern the fate of the Proto-Indo-Iranian first-series palatal consonants, *ć and *dź:
Document 2: A Journey Beyond the Three Seas: "A Journey Beyond the Three Seas" was the first Russian literary work to depict a strictly commercial, non-religious trip. Prior texts were pilgrimage texts, which depicted travel to holy sites and were more standardized, dry and conventional. The author visited the Caucasus, Persia, India and the Crimea. However, most of the notes are dedicated to India, its political structure, trade, agriculture, customs and ceremonies. The work is full of lyrical digressions and autobiographic passages. There is a strong individual, authorial presence. Its last page is in Turkic and the broken Arabic language; these are, in fact, typical Muslim prayers, indicating that Nikitin might have converted to Islam while he was in India, although his lapse from Christianity bothered him as he mentions several times in the text.
Document 3: Ahmad Saeed Kazmi: Syed Ahmad Saeed Kazmi (1913 – 4 June 1986, ) was scholar and Sufi living in Multan. He is known for his contribution to the Pakistan Movement, Urdu translation and explanation (Tafseer) of Quran, and Dars-e-Hadith. His tomb sits next to Multan's 18th century Shahi Eid Gah Mosque.
Document 4: Quran: One of the notable authors of esoteric interpretation prior to the 12th century is Sulami (d. 1021) without whose work the majority of very early Sufi commentaries would not have been preserved. Sulami's major commentary is a book named haqaiq al-tafsir ("Truths of Exegesis") which is a compilation of commentaries of earlier Sufis. From the 11th century onwards several other works appear, including commentaries by Qushayri (d. 1074), Daylami (d. 1193), Shirazi (d. 1209) and Suhrawardi (d. 1234). These works include material from Sulami's books plus the author's contributions. Many works are written in Persian such as the works of Maybudi (d. 1135) kash al-asrar ("the unveiling of the secrets"). Rumi (d. 1273) wrote a vast amount of mystical poetry in his book Mathnawi. Rumi makes heavy use of the Quran in his poetry, a feature that is sometimes omitted in translations of Rumi's work. A large number of Quranic passages can be found in Mathnawi, which some consider a kind of Sufi interpretation of the Quran. Rumi's book is not exceptional for containing citations from and elaboration on the Quran, however, Rumi does mention Quran more frequently. Simnani (d. 1336) wrote two influential works of esoteric exegesis on the Quran. He reconciled notions of God's manifestation through and in the physical world with the sentiments of Sunni Islam. Comprehensive Sufi commentaries appear in the 18th century such as the work of Ismail Hakki Bursevi (d. 1725). His work ruh al-Bayan (the Spirit of Elucidation) is a voluminous exegesis. Written in Arabic, it combines the author's own ideas with those of his predecessors (notably Ibn Arabi and Ghazali), all woven together in Hafiz, a Persian poetry form.
Document 5: Wali Mohammed Wali: Before Wali, South Asian Ghazals were composed in Persian, almost being replicated in thought and style from the original Persian masters like Saa'di, Jami and Khaqani. Wali began, using not only an Indian language, but Indian themes, idioms and imagery in his ghazals. It is said that his visit to Delhi in 1700, along with his divan of Urdu ghazals created a ripple in the literary circles of the north, inspiring them to produce stalwarts like Zauq, Sauda and Mir.
Document 6: Western Iranian languages: The Western Iranian languages are a branch of the Iranian languages, attested from the time of Old Persian (6th century BC) and Median.
Document 7: Iranian languages: Old Persian is the Old Iranian dialect as it was spoken in south-western Iran by the inhabitants of Parsa, who also gave their name to their region and language. Genuine Old Persian is best attested in one of the three languages of the Behistun inscription, composed circa 520 BC, and which is the last inscription (and only inscription of significant length) in which Old Persian is still grammatically correct. Later inscriptions are comparatively brief, and typically simply copies of words and phrases from earlier ones, often with grammatical errors, which suggests that by the 4th century BC the transition from Old Persian to Middle Persian was already far advanced, but efforts were still being made to retain an "old" quality for official proclamations.
Document 8: Sultan Bahu: Sultan Bahu (‎; also spelled Bahoo; ca 1630–1691) was a Sufi mystic, poet, and scholar active during the Mughal empire mostly in the present-day Punjab province of Pakistan. He belonged to Qadiri Sufi order, and founded the mystic tradition known as Sarwari Qadiri.
Document 9: Iranian languages: In addition to Old Persian and Avestan, which are the only directly attested Old Iranian languages, all Middle Iranian languages must have had a predecessor "Old Iranian" form of that language, and thus can all be said to have had an (at least hypothetical) "Old" form. Such hypothetical Old Iranian languages include Carduchi (the hypothetical predecessor to Kurdish) and Old Parthian. Additionally, the existence of unattested languages can sometimes be inferred from the impact they had on neighbouring languages. Such transfer is known to have occurred for Old Persian, which has (what is called) a "Median" substrate in some of its vocabulary. Also, foreign references to languages can also provide a hint to the existence of otherwise unattested languages, for example through toponyms/ethnonyms or in the recording of vocabulary, as Herodotus did for what he called "Scythian".
Document 10: Sarmad Kashani: Sarmad Kashani or simply as "Sarmad" (ca 1590–1661) was a Persian speaking Armenian mystic and poet who travelled to and made the Indian subcontinent his permanent home during the 17th century. Originally Jewish, he may have renounced his religion to adopt Islam. Sarmad, in his poetry, states that he is neither Jewish, nor Muslim, nor Hindu.
Document 11: Iranian languages: It is possible that other distinct dialect groups were already in existence during this period. Good candidates are the hypothethical ancestor languages of Alanian/Scytho-Sarmatian subgroup of Scythian in the far northwest; and the hypothetical "Old Parthian" (the Old Iranian ancestor of Parthian) in the near northwest, where original *dw > *b (paralleling the development of *ćw).
Document 12: Mahsati: As an eminent poet, she was composer of quatrains (ruba'is). Originated from Ganja, she was said to have associated with both Omar Khayyam and Nizami. She is also said to have been a companion of Sultan Sanjar. Her alleged free way of living and peddled verses have stamped her as a Persian Madame Sans-Gêne . Her purported love affairs are recounted in the works of "Jauhari of Bukhara".
Document 13: Nader Naderpour: Among many Iranian poets who shaped up the New Persian Poetry or New Poetry (in Persian: "She'r-e Now"), Ali Esfandiari aka Nima Yooshij, Parviz Natel Khanlari, Nader Naderpour, Forough Farrokhzad, Mehdi Akhavan Saless, Sohrab Sepehri, Fereydoon Moshiri, Siavash Kasrai, Ahmad Shamlu, Hushang Ebtehaj, and Mohammad-Reza Shafiei Kadkani are considered to be the most famous, skilful, and professional. Though Nima Yooshij (1896–1960) is known as the Father of New Persian Poetry, aka Nimaii Poetry or "She'r-e Nimaii", according to a number of eminent and highly respected literary and poetry scholars Nader Naderpour is considered as the first Iranian poet who opened up exciting vistas of the new Persian poetry.
Document 14: Iranian languages: What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the 4th century BCE lasting through the 9th century. Linguistically the Middle Iranian languages are conventionally classified into two main groups, Western and Eastern.
Document 15: Iranian languages: The multitude of Middle Iranian languages and peoples indicate that great linguistic diversity must have existed among the ancient speakers of Iranian languages. Of that variety of languages/dialects, direct evidence of only two have survived. These are:
