As a Hadith Transmitter
The scholars of rijal have regarded Hammad b. 'Uthman al-Nab as one of the People of Consensus, who are regarded by all rijal experts as reliable. Hammad is also praised by such words as erudite (al-fadil), great, and noble.
There is disagreement among scholars as to whether Hammad b. 'Uthman is the name of one and the same hadith transmitter or there were two hadith transmitters with the same name. Many scholars, including al-Khoei, 'Abd Allah al-Mamaqani, and Muhammad Taqi Shushtari, believe that Hammad b. 'Uthman is the name of one hadith transmitter. No matter what position one takes on this issue since there is no unreliable hadith transmitter called Hammad b. 'Uthman, the hadith with the name Hammad b. 'Uthman in its chain of narration would be authentic—if the rest of the transmitters were reliable.
There are about two-thousand hadiths quoted by Hammad b. 'Uthman in Shi'a hadith collections. Most of these hadiths are related to fiqh, and many of them have to do with Imamate. Hammad quoted many hadiths from Imam al-Sadiq (a) directly, and about one-hundred hadiths from other hadith transmitters (mostly from 'Ubayd Allah b. 'Ali al-Halabi).
Hammad had a book that contained his hadiths. This book seems to have been extant until the time of al-Sayyid b. Tawus, who calls it an Asl, though it may not have been an Asl in its technical meaning.
