According to the author of this article, hadiths are divided to four main groups: doctrinaire, historical, commandments, and moral. Among them, the historical and doctrinaire hadiths haven’t been studied though they are very important. He believes that when the religious and deviant tendencies of some of hadiths are pointed out in the books of men, they turn out to be questionable automatically. But that’s not the whole story because even the ones without any special orientations might unintentionally contain either changed or fabricated historical or doctrinaire stories. Therefore, in the following paper, the author has a brief look at this group of hadiths, and for every case provides some examples.
