How sound is the hadith, "Indeed, Allah granted the Prophet Sheth, peace be upon him, fifty scriptures," and what are its chain of transmission (sanad) and text (matn)?

The Hadith (definition) that mentions "fifty scriptures were revealed to Seth" was narrated by Ibn Hibban with a chain of transmission that includes Ibrahim ibn Hisham, who is a fabricator of Hadith. Al-Zayla'i mentioned it in "Takhrij Ahadith al-Kashshaf" and stated that Al-Hakim, Al-Tabarani, Ahmad, and Ishaq narrated it through various chains, all of which contain weak narrators. Furthermore, Ibn al-Jawzi included it in "Al-Mawdu'at" (Fabricated Hadith). Therefore, the least that can be said about this Hadith is that it is weak.
