#Sincerely a behdin/zartoshti 🙃

[suraanahita]

Astvat.ərəta is one of the eschatological sons of Zarathustra (viz. Pahlavi narrative of the 3 “saviours” - or more natively/properly the 3 benefactors or saošyant), and he has nothing to do with Muhammad, like at all. He is not manifest yet, as THE saošyant who will incur frašokərəti, the final renovation of the cosmos. He is foreseen to be conceived in Lake Kąsaoya that preserves the seed of Zarathustra (ex: Vendīdād 19.5), which draws its waters from the river Haētuman (likely the Helmand River). Zam Yašt, Yt 19.92:

āat̰astvat̰-ərətō fraxštāite

haca apat̰ kąsaoyāt̰

aštō mazdā̊-ahurahe 

vīspa-taurvayā̊ puϑrō

vaēδəm vaējō yim vārəϑraγnəm

yim barat̰taxmō ϑraētaonō

yat̰ažiš-dahākō jaini :

“When Astvat.ərəta shall come forth, out from the lake Kąsaoya, the messenger of Mazdā-Ahura, the son of Vispā.taurvairī, brandishing his Obstruction/Obstacle smashing weapon, which the mighty ϑraētaona (Pers. Fereydūn/Faridūn) carried (too) whence the Aži Dahāka (Pers. Zahak) was smashed.”
