Mustadrak al-Hakim — Hadith 2745M5

Abu Bakr Muhammad bin Ishaq al-Imam said: I asked Muhammad bin Yahya about this chapter, and he said: "In my view the hadith of Isra'il is sahih (authentic)." I said to him: Sharik has also narrated it? He asked: Who narrated it (from him)? I said: Ali bin Hujr narrated it to us. And I mentioned to him the hadith of Yunus bin Abi Ishaq and of some of the other narrators who narrated it from Abu Ishaq. Then I said to him: Shu'bah and al-Thawri narrated it from Abu Ishaq, from Abu Burdah, from the Prophet (peace and blessings be upon him). He said: Yes, the two of them narrated it this way, but they (the hadith scholars) would at times narrate a hadith as mursal, until when they were asked "From whom?" they would then narrate it with a connected (musnad) chain.
