and he was followed by al-Ḥārith ibn ʿUmayr in "Adab al-Bukhārī" (1194) and in "Tārīkh al-Kabīr" (2/1/389). This Zuhayr was mentioned by a group among the Companions, and Ibn Abī Ḥātim affirmed from his father that his ḥadīth is mursal, and likewise Ibn Ḥibbān mentioned him in "Thiqāt al-Tābiʿīn." I said: In any case, the ḥadīth is authentic with a connected isnād, and the anonymity of the Companion does not harm it. The first part of it is supported by a ḥadīth from ʿAlī ibn Shaybān. It was recorded by al-Bukhārī in "al-Adab al-Mufrad" (1192) and by Abū Dāwūd (5041) through the route of ʿUmar ibn Jābir al-Juʿfī from Waʿlah ibn ʿAbd al-Raḥmān ibn Wathāb from ʿAbd al-Raḥmān ibn ʿAlī ibn Shaybān from his father. This isnād is not bad for supporting evidence, ʿAbd al-Raḥmān ibn ʿAlī is trustworthy, and those below him are accepted by al-Ḥāfiẓ Ibn Ḥajar. There is another supporting ḥadīth from Ibn ʿAbbās, elevated. It was recorded by Ibn ʿAdī in "al-Kāmil" (folio 82/2, 83/2). However, its isnād is weak, as it includes al-Ḥasan ibn ʿAmārah, who is abandoned. In its meaning is what ʿAbd al-Jabbār ibn ʿUmar narrated from Muḥammad ibn al-Munkadir from Jābir, who said: "The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) forbade sleeping on a roof that is not enclosed." It was recorded by al-Tirmidhī (2/139) who said: "A strange ḥadīth; we do not know it from the ḥadīth of Muḥammad ibn al-Munkadir from Jābir except through this route, and ʿAbd al-Jabbār ibn ʿUmar is weak."
