As for Abū Muḥammad Ibn Ḥazm, he virtually proclaimed his own lack of knowledge when he wrote in the Kitāb al-Farāʾiḍ of his work al-Iṣāl: “Muḥammad b. ʿĪsā b.

Hence, nothing of his verdicts should be accepted except where they coincide with those of the well-known earlier imams—or at the very least do not contradict them.
With this, the discussion of the two ḥadiths that Ibn Ḥazm weakened in the first section of the six authentic reports, together with a demonstration of his error concerning them, is concluded.

Concerning the second ḥadith in this section, Ibn Ḥazm explicitly remarked, as cited earlier, “No one knows who related it!”
Yet more than ten of the renowned ḥadith masters transmitted it in their compilations, from
