Abu Hatim al-Razi: Not satisfactory, and once: A trustworthy Shaykh
Abu Hatim ibn Hibban al-Busti: A denier of hadith, he narrates from the trustworthy, inverted things that seem fabricated. It is not permissible to rely on him if he narrates alone due to his poor memory. However, if what he narrates agrees with the trustworthy narrators, then there is no harm in it.
