(Imam al-Hakim says that) I heard Abu Ali al-Hafiz say: The mention of Sayyiduna Jabir (may Allah be pleased with him) in its chain is an error. Then he narrated it to us in mursal form through the chain of Muhammad bin Ishaq al-Thaqafi from Amr bin Dinar: "The Prophet (peace and blessings be upon him) was in the Cave of Hira," and then mentioned the hadith in the same way. All the narrators of the first, connected hadith are trustworthy, and I have built this book upon the principle that an addition from a trustworthy narrator is accepted. As for the prostration in "Read in the name of your Lord", Imam Muslim recorded it through the chain of Abu al-Tahir, from al-A'raj, from Sayyiduna Abu Hurayrah (may Allah be pleased with him).
