he heard Amir al-Mu'minin (as) say: 'After the holy Prophet people become of three kinds. One group went to a divinely well guided scholar. Allah had given him such a high degree of knowledge that made him independent of the knowledge of the others. The second group was the ignorant group, who claimed to have knowledge but in fact they had no knowledge. This was an egotist group. The worldly attractions had made them to lose sight of the truth and to mislead other people. The third group consisted of those people who learned from a divinely guided scholar who taught them for the sake of Allah and for their salvation. It then was obvious that those who claimed (to be scholars while, in fact, they were not scholars) and those who forged certain matters falsely were destroyed.'
