The last question from our brother Ayman is: Are there books that mention what is authentic from the narrations of the sahaba and the tabi'in?

As for the books and main sources on this, which a student of knowledge should refer to, there are many compilations on this.

Among them are old admonitions like the books of Sa'id ibn 'Arouba, as well as the books of Waki' and Sufyan.

Also, the books that were written during that period, or close to it, like the Muwatta of Imam Malik.

And the books that came after that or were from the same period, like the Musannaf of 'Abd al-Razzaq, and after that the Musannaf of Ibn Abi Shayba.

Al-Awsat by Ibn al-Mundhir, as well as al-Sunan al-Kubra and Ma'rifat Sunan al-Athar by al-Bayhaqi.

Also, the books of Ibn Abd al-Barr, may Allah have mercy on him, and also al-Tamhid, and the books of tafsir that focus on the fiqh of the sahaba.

In them are likely found the fiqh of the tabi'in, such as the book of Ibn Jarir al-Tabari, and the tafsir of Ibn Abi Hatim.

And the tafsir of Abd bin Humayd, and the tafsir of Ibn al-Mundhir, and the tafsir.

Also, some of the imams, may Allah's mercy be upon him, among the later scholars who focused on the chains of narration, like al-Baghawi, may Allah's mercy be upon him, who is considered later compared to those before him.

There are also compilations that came after that, which focused on some narrations, and they are somewhat late, and they pay attention to these narrations, like the books of history.

The later historical books that include some chains of narration and contain some narrations, and for this reason we say that referring back to these original sources is better. As for the later books, these books are relied upon.

On the narrations and the authentic reports transmitted from the sahaba and the tabi'in, I do not know of a comprehensive book.

In this field, there have been attempts by some contemporary scholars, but they are limited attempts, meaning they are not referred to because of their shortcomings in this area, but they are still attempts. And there are those who tried to compile in this.

And I think al-Kattani did compile, al-Muntasir al-Kattani compiled in this field, but he selected from al-Mughni and also from al-Hazm, but without chains of transmission and without judging them.
