Professor Ansarian: the completion and sublimity of the religion of Islam is closely tied with the " Mahdiism school of thought ", as it has been mentioned in a prophetic Hadith which says that the failure to know and the Imam of the time and the divine authority at any time brings about a volte face and regression of the humankind to the era before the advent of Islam and the age of ignorance. "whoever dies without knowing the Imam of the time, it is as if he died during the age of ignorance and the era before the advent of Islam", (مَنْ ماتَ وَ لَمْ يَعْرِفْ إمامَ زَمانِهِ مَاتَ مِيتَةً جَاهِلِيَّة؛).
Kamaaluddin: 401, Sahih Muslim/ 3: 147
