What is the authenticity of the statement of the Shaykh al-Islam in the introduction to the Tafsir

The questioner : The Shaykh al-Islam says in the introduction to the Tafsir: "If the mursal reports have multiple chains and are free from deliberate or accidental collusion, they are certainly authentic." Is this statement correct?

The Shaykh : If we look at the wording of his statement with precision and careful attention, it is correct. So repeat it to me so that I can focus on that specific wording.

The questioner : You mean collusion.

The Shaykh : In order to avoid collusion, some of the scholars of hadith mentioned that if we look at two mursal reports of a mursal hadith and find that each of the mursal narrators did not live in the same country as the other, and it is more likely than not—and the likelihood is sufficient in such matters—that one of them did not meet the other, or at least did not travel to the country where the other mursal narrator was, then by such tracing and by what the Imam al-Shafi'i also said—and it seems he is referring to what I mentioned—that if the teachers of each of the mursal narrators are different from the teachers of the other, this makes us confident that there is no collusion and no meeting in narrating from a specific person, so the narration returnsThe Shaykh : to the narration of a single teacher.
