Hisham Ibn Salem is one of the most trusted Shiite narrators and he is one of the companions of Sadegh and Kazem Imams (as). He was the author of the asl and books of Tafsir, Ascension and Hajj. Some have considered his books as koleini sources. For example, his commentary book has been considered as one of the alkaffi commentary sources. it seems His hadiths have reached Kolini through later works. Examining the sanad of all the hadiths of Hisham Ibn Salem in the kafii book and Tahdhib Al-Ahkam of Sheikh Tusi shows that None of Hisham Ibn Salem's books has been a kolini source in obtaining hadith Rather, his narrations have been made available to Kolini through other books such as the books of Muhammad ibn Abi Umayr, Hasan ibn Mahboob, Husayn ibn Sa'id and Ahmad ibn Muhammad ibn Isa. These narrators had access to the books of Hisham bin Salem and The hadiths have reproduced in their books. Also Hadiths have been narrated to them orally by Hisham bin Salem and They have written in their books. But its number is small.
