To what extent are the narr rative s of Abu Ishaq established from a Hadith and historical perspective, what is correct and incorrect in them, and who are the contemporary imams specialized in this field who can clarify the points of error?

Muhammad ibn Ishaq was authenticated by many Hadith scholars such as Imam Ahmad, Ibn Ma'in, Al-Ijli, and Ibn Numayr. Muslim, Ahmad, and the compilers of the Sunan narrated from him, and Al-Bukhari narrated from him in a suspended (ta'liq) manner. He was a mudallis (one who conceals the source of a narration), so what he explicitly stated as having heard directly (sarradah bi al-tahdeeth) was accepted from him, but what he did not explicitly state as such was not accepted. Al-Dhahabi said that he was truthful (saduq) and one of the oceans of knowledge, and his Hadith is hasan (good).
