Reviewing the Naser al-Ghafari doubts on the Shia hadith collections

Knowing the hadith technical terms and great features in this field are two main branches in this field, and without that we can not discern the true Hadith practice it. Naser al-Ghafari, a Wahhabi scholar, maintains that the Shia hadith deprive these features, believing that there is no valid Hadith in Shia sect. he argues that the Shia established the hadith science in the fourth century and could not discover the valid narrator in Hadith. Also, the Shia started the hadith science technically at the 7th century, trying to escape from Ibn Taymiyyah criticisms. Answering to these doubts, we must say that the first hadith collection in Shia was compiled in the first century by Obeidollah Bin Abi Rafe. Al-Tusi, the great Shia scholar named this book in his works. The Shia Hadith science had started 200 years before the other sects in Islam, differentiating between the valid and invalid Hadiths. This methodology was common between the Shia in the period before Imam Sadegh's time. So, the Ghafari's doubts on the Shia hadiths are baseless.
