Who narrated from Abd al-Razzaq in his Musannaf, and is he trustworthy, especially given that some believe he is Ishaq ibn Ibrahim al-Dabari and that he narrated many objectionable things from him, and is it true that he heard from him when he was seven years old?

The famous books of Sunnah reached us through narration (riwayah). A book may have more than one narration attributed to its author. Sometimes, the narrator repeats the author's name at the beginning of each chain of transmission (isnad). The printed edition of Musannaf Abd al-Razzaq was compiled from several narrations, including the narration of Ishaq ibn Ibrahim ibn Abbad al-Dabari. Al-Dabari's narration is considered authentic by most Muhaddithun (hadith scholars) unless it contradicts the narrations of trustworthy narrators. His hearing of it in his youth makes it stronger than 'wijdada' (finding a written text without hearing it from the author), and 'wijdada' is accepted by some early scholars and most later scholars. Al-Suyuti mentioned that acting upon it is obligatory when confidence in its narration is attained, because if acting upon it were to depend on narration, it would close the door to acting upon transmitted knowledge due to the difficulty of fulfilling its conditions. Ibn Khair al-Ishbili indicated that Al-Uqaili authenticated his narration from Abd al-Razzaq. As for the hadiths in which Al-Dabari contradicted trustworthy narrators, they are very few, and Abu Abd Allah ibn Mufarrij al-Qurtubi collected them in a treatise. The reason for the widespread fame of Al-Dabari's narration is the narrators' keenness for a high chain of transmission, given that he lived a long time after Abd al-Razzaq's death.
