Abu Ahmad ibn Adi al-Jarjani: He narrates unique narrations
Abu Hatim ibn Hibban al-Busti: He errs
Abu Dawud al-Sijistani: He did not narrate from him
Ibn Hajar al-Asqalani: Saduq (truthful) but has some mistakes
al-Dhahabi: Thiqah (reliable) and narrates many Hadiths from al-Walid, and once: Saduq Sahih al-Kitab, some people criticized him without proof, and his unique narrations from al-Walid are not denied, as he narrates more than him
Authors of Tahrir Taqrib al-Tahdhib: Saduq Hasan al-Hadith, and he is closer to being trustworthy, and we do not know where the author got his saying that he has mistakes
