In a broad sense, the age of ignorance refers to the long historical stage from the birth of Zuadan to Muhammad's appointment as a prophet.
In a narrow sense, it only refers to about 100 years before Muhammad spread Islam. Its connotation is that there is no fate, no inspired prophet, no revelation and no classics in the Arabian Peninsula.
Muhammad spread the recognition that the Lord is the only religion, called on people to abandon all religious concepts except Islam, especially the concept of worshipping gods and idols, and announced that Islam would cancel the past religious consciousness and replace it. Therefore, although the concept and division of the obscurantism era are wide, narrow and short, the rise of Islam marks the end of the obscurantism era. During the period of obscurantism, Arabs in the north, including Hijaz and Najid, mostly lived a nomadic life, with no ancient culture to test and no calligraphy system of their own. The materials of this period were limited to legends, legends, proverbs and poems, but these things were only recorded in the second and third centuries of the Islamic calendar. It was not until the Muhammad period that we had our own calligraphy system. A classic Islamic language evolved from Hijaz dialect. After replacing Yemeni dialect, it developed into beautiful and standard Arabic. Therefore, the previous historical periods are collectively referred to as the period of ignorance.
