After that they left him alone, and he therefore grew up illiterate. Some, however, say that he could in fact write, albeit with a shaky hand (1).
Al-Khaṭīb al-Baghdādī (2) transmitted through his chain from his forebears two fabricated ḥadīths: the first disparages the Banū Umayyah while praising the caliphs of Banū al-ʿAbbās; the second forbids cupping on a Thursday.
