—through Ismāʿīl ibn ʿUlayyah, who said, “ʿAbd al-ʿAzīz ibn Ṣuḥayb narrated it to us from (Anas) in these very words,” and this is the version preserved by al-Bukhārī.
Others transmit the wording as wanḥasar (“it slipped back”) instead of ḥasar (“he lifted it”). Al-Ṭabarānī also recorded the report, as noted in Fatḥ al-Bārī, and al-Nasāʾī related an abridged form that merely mentions the uncovering.
As for the legal issue itself—namely, that the ʿawrah consists only of the two private parts—the Ẓāhirī school adopted it, and one narration attributes it to Aḥmad and to Mālik, as al-Nawawī states in Fatḥ al-Bārī; he likewise cites it in his commentary on Muslim as an opinion found among Mālik’s followers. Abū Saʿīd al-Isṭakhrī of the Shāfiʿīs held it, and al-Suyūṭī later favored it, as will be mentioned.
Ibn Ḥazm says: “It is the position of Ibn Abī Dhʿīb, Sufyān al-Thawrī, and Abū Sulaymān, and it is the view we adopt; indeed, it was the opinion of the majority of the early generations.”
He then transmitted from Jubayr ibn al-Huwayrith who said: “I saw Abū Bakr al-Ṣiddīq standing on the hill of Qazḥ, calling out, ‘People, begin the day!’ while I could see that his thigh was uncovered.”
Al-Bukhārī likewise narrated—through Mūsā ibn Anas ibn Mālik—an account of the Day of al-Yamāmah in which he said: “Anas came to Thābit ibn Qays ibn Shammās, whose thighs were exposed as he was applying embalming perfume in preparation for death.”
ʿAṭāʾ ibn al-Sāʾib said: “I entered upon Abū Jaʿfar—that is, Muḥammad ibn ʿAlī ibn al-Ḥusayn ibn ʿAlī ibn Abī Ṭālib—while he was burning with fever and his thighs were uncovered…” and he went on to narrate the remainder of the report.
