In the study, the tafsir narrations narrated by tabi’un mufassir Mujahidibn Jabr from his teacher Ibn Abbas are discussed. The narrations in question are examined in terms of their content, compliance with the opinion of Mujahid, and Tabari's preference for them. The study is carried out on the narrations contained in the suras Baqara and Al-i-Imran, on the basis of Tabari's tafsir called Camiu'l-Bayan an Ta'wili Ayi'l-Qur'an. When the relevant part of the work in question is scanned, it is seen that Mujahid conveyed the explanation in the interpretation of some verses from the companions. When the relevant section of the work in question is scanned, it is seen that Mujahid conveyed the explanation in the interpretation of some verses from the companions. As far as we can see, the companions to whom he refers differ. However, it is understood that many of these transfers are based on Abdullah. The reason for this, in our opinion, is the teacherstudent relationship between the two. We have examined the transmissions of Mujahid from his teacher in two headings in the form of his transmissions about explaining the verses and the knowledge of the Qur'an. The first title; We divided it into two in the form of transfers related to fiqh and word explanation. The fiqh explanations that Mujahid passed on from his teacher are many compared to the others. Mujahid also has his own explanations for some of the verses he narrates about. In some of these explanations, Mujahid thinks the same as his teacher, while in some of them he objects to his teacher. Sometimes, the explanation made by Mujahid is in the form of completing the information he conveyed from his teacher. The explanation made by Mujahid is in the form of completing the information he conveyed from his teacher. As for Mujahid's word-by-word explanations from Ibn Abbas, in such narrations, sometimes a word of the verse and sometimes a phrase is explained, the lexical meaning of the word or the meaning it means is emphasized. We presented the second title under three subheadings. Asbab al-nuzulnarrations are more than others, we have dealt with them separately. We examined naskh and muhkamat - mutashabıhatin one heading, grammar, byword and ambiguous words in another heading with examples.In some of the transplants we examined in the study, we found that Mujahid shared the same opinion as his teacher, and in others, he thought differently. In the same way, we have seen that Tabari acted selectively in these transmissions, preferring some narrations and not others.
