An excerpt from the book Zukhrat al-Riyāḍ by the Bulgar–Saqsin author of the 12th century, Sulaymān as-Suvarī as-Saqsinī:
“Allah — in Syriac Īlā, in Hebrew ʾĪlā, in Persian Pādishāh, in Khwarazmian Būmanānad, in Greek Tamhīsā, in Indian Shītīsā, in Turkic Biyāt, in Chigil Ugān, in Oghuz Ulug, and in Bulgar Tynz (Tunz?). These are the names of Allah among those who speak [these languages].”
A few remarks.
1. Many of the designations of Allah (including some Turkic ones) were clearly distorted by later copyists.
2. Different Turkic dialects are distinguished as Turkic, Chigil, Oghuz, and Bulgar.
The Chigil and Oghuz designations of Allah are transmitted correctly. The “Turkic” form بِیَات Biyāt should be vocalized as بَیَات and read Bayāt. The Bulgar form طِنز Tynz or طُنز Tunz should be written and vocalized either as طَنرِ Tanrı (which brings it closer to Ottoman and modern Turkish pronunciation) or as طُنرِ Tunrı (which brings it closer to the modern Chuvash pronunciation Tură).
