Imam Muhammad bin Abd al-Rahim (may God have mercy on him) lived at the end of the second century and the middle of the third century AH, characterized by the maturity and prosperity of the scientific movement. Therefore, competition in seeking knowledge and traveling for it was a visible matter, and classification, teaching, and travel were some of the prominent features of the people of that era. He was a student of the best scholars of his time, the most distinguished of whom was Imam Ahmad bin Hanbal (may God have mercy on him), and he took great care of his company. He, may God have mercy on him, was praised by scholars and eminent imams. He has narrations in the books of the Prophetic Sunnah, such as the Sahih of Imam Al-Bukhari, the Sunan of Imam Abi Dawood, the Jami` of Imam Al-Tirmidhi, the Musnad of Imam Ahmad, and the Sunan of Imam Al-Nasa'i Minor and Great, the Sahih of Imam Ibn Khuzaimah, the Sahih of Imam Ibn Hibban, and Al Mustadrak on the two Sahihs by Imam Al-Hakim, as well as in Al-Muntaqa by Ibn Al-Jarud, Sunan al-Bayhaqi al-Kubra, Sunan al-Daraqutni, Musnad al-Bazzar, the three dictionaries of al-Tabarani, and much more. Imam Muhammad bin Abd al-Rahim (Sa'iqa) was considered one of the imams of al-Jarh and al-Ta'deel who relied on their sayings, through his knowledge of the narrators' names and their kinships, his control over them, his attention to the narrators' headphones, his proof of that, and his approval of the audience of critics in documenting or weakening the narrators and his knowledge of them. Through a review of his students, we found that many of them had a leading position in the sciences of Islamic law, as they learned a lot from the sciences of their Sheikh. The follower of the sciences of Imam Muhammad bin Abd al-Rahim (Thunderbolt) will find that his critical statements about narrators, archeology, and his sciences drew a clear approach for students of knowledge who came after him, and left a great scientific impact on their upbringing and their emergence in various sciences, especially the science of hadith, narration, and knowledge.
