How is the authenticity of the attribution of manuscripts to scholars like Al-Bukhari and Ibn Taymiyyah verified, and how is it differentiated from what might be interpolated or forged? Is reading them easy or difficult? And what do they do if parts of them are effaced?

The subject of manuscript verification, study, documentation, and ensuring their authenticity is a science taught in universities and requires studying the works of specialists. Among the most important books in this field are: "Tahqiq al-Nusus wa Nashruha" (Verifying and Publishing Texts) by Abd al-Salam Harun, "al-Makhtut al-Arabi" (The Arabic Manuscript) by Abd al-Sattar al-Hawlaji, "Manhaj Tahqiq al-Nusus wa Nashruha" (Methodology for Verifying and Publishing Texts) by Hammoudi al-Qaysi and Sami al-Ani, and "Tahqiq al-Turath" (Verifying the Heritage) by Abd al-Hadi al-Fadli.
