Is there a Hadith that is recited after finishing Surat At-Tin, which includes the saying "Bila shak wa ashhad (Undoubtedly, and I bear witness)," and what is its authenticity, and where can it be found?

Al-Tirmidhi and Al-Albani declared the Hadith narrated by an unidentifiable Bedouin from Abu Hurairah as weak. This Hadith states that whoever recites the end of Surat At-Tin should say: "Yes, and I am among those who bear witness to that." The reason for its weakening is the anonymity of the Bedouin who narrated the Hadith. Consequently, this Hadith is not acted upon.
