that he heard the Messenger of Allah ﷺ say: “When the servant prostrates…”—and the rest of the report. Al-Hakim erred when he asserted that both Imams transmitted it; it is actually unique to Muslim. (1) Meaning: the hair is braided and twisted. Ibn al-Athir explains: “If the hair is loose it falls to the ground during prostration, so its owner receives the reward of prostrating with it; but when it is tied up it is as though it did not prostrate. The Prophet likened this to a *maktuf* (someone whose hands are bound), because such hands do not reach the ground in prostration.” I would add that the ruling appears to concern men only, not women, as al-Shawkani relates from Ibn al-‘Iraqi. (2) The report comes from Abdullah ibn Abbas: he saw Abdullah ibn al-Harith praying with his hair gathered behind his head, so he stood and untied it. When the prayer ended, Ibn al-Harith said, “Why did you touch my head?” Ibn Abbas replied, “I heard the Messenger of Allah ﷺ say…” and he cited the hadith. Narrated by Muslim 2/53; Abu Awana 2/74; Abu Dawud 1/105; al-Nasa’i 1/167; al-Darimi 1/320; and al-Bayhaqi 2/108–109—all through Ibn Wahb, except al-Darimi, who transmits it via Bakr ibn Mudir; both chains go back to Amr ibn al-Harith, from Bukayr, from Kurayb the freedman of Ibn Abbas. Layth ibn Saad corroborated them, adding Shuba, another freedman of Ibn Abbas, alongside Kurayb in the chain.
