and weakening [the ḥadīth] is not well done by someone who has clung to it in old age or inexperience, but rather it is well done by those specialized in it who have spent their lives and grown old with it, until the authentic prophetic ḥadīth runs in their veins and becomes an inseparable part of their lives. As for those who are not like that, there is no doubt that they will fall into the misfortune of rejecting authentic ḥadīths and weakening them, or the opposite, as is the case with the people of whims and innovations. We ask Allāh for safety. To make the topic more accessible to the readers' minds, it is necessary to present the ḥadīth from the three chains that the virtuous shaykh weakened, so that the truth may appear to them in the clearest form; because I had previously presented it in a summarized form and attributed it to some of my books without detailing its chains. So I say: the first [chain]: from Yaḥyá ibn Ayyūb from Yazīd ibn Abī Ḥabīb from ʿAbd al-Raḥmān ibn Shamāsah from Zayd ibn Thābit. It was narrated by al-Tirmidhī (3949), Aḥmad (5/185), Ibn Abī Shaybah (5/325), al-Ḥākim (2/229), and al-Ṭabarānī in "al-Muʿjam al-Kabīr" (5/175-176), and Ibn ʿAsākir in "Tārīkh Dimashq" (1/112-113, Damascus edition) through the route of Yaḥyá ibn Isḥāq al-Sayliḥīnī and Jarīr ibn Ḥāzim, both from Yaḥyá ibn Ayyūb with it. The second [chain]: from Ibn Lahīʿah from Yazīd ibn Abī Ḥabībah with it. It was narrated by Aḥmad (5/324), al-Fasawī in "al-Maʿrifah" (2/301), al-Ṭabarānī (5/176/4934), and also Ibn ʿAsākir (1/114 and 115) from routes including ʿAbd Allāh ibn Wahb from him. Al-Fasawī and Ibn ʿAsākir paired ʿAmrū ibn al-Ḥārith with Ibn Lahīʿah, and Ibn Ḥibbān indicated this in his following narration. The third [chain]: ʿAmrū ibn al-Ḥārith—and Ibn Salm mentioned another with him—from Yazīd ibn Abī Ḥabībah with it
