In the Sudanese Islamic cultural structure, it did not form any meaning. Hence, Islamic Arab culture emerged as a pure culture, without the slightest influence from any of the locally recognized influences, as was the case in the Levant, Iraq, and Egypt before the Islamic conquest. This development was no less than its counterpart in other Islamic countries, where Arab features and Arab culture spread. The emergence of Islamic civilization features played a role in the complete fusion between the incoming Islamic traditions, with all their spiritual influences, human values, and authentic traditions and customs, and the prevailing local traditions in all aspects, in the systems of governance, in social life, and in Islamic culture. What is remarkable about this is the emergence of a form of Islamic civilization, where Sudan had to respond to this development after Islamic influences became widespread. This is because, without a doubt, that fusion has greatly left its mark on the Arabism and current culture of Sudan. Today, we find a clear structure in Arab culture in Sudan in terms of language and race. Some regions are predominantly Arab, while others are characterized by an African nature, and a third group combines both cultures. Considering this, it can be said that this cultural and anthropological diversity is due to the nature of Arab migration to Sudan, as some tribes merged and dissolved into the local population, who belonged to multiple races, most notably the Hamitic people. At the same time, we find an Arab group that has preserved its purity, nationality, and language. However, we cannot overlook the impact of local conditions on the adaptation of Sudanese Arabism. The environment, by its nature, in turn, influenced the nature, stability, and assimilation of these tribes, just as some social factors helped some of these tribes to melt into the local crucible. Thus, Arab tribes alone were not the first pioneers in spreading Arab Islamic culture in Sudan. Rather, people from among the Arabs or remnants of warring armies fleeing political pressure, or preachers who were instrumental in spreading Islamic teachings, which became widespread in northern Sudan and even reached the southern provinces, including Province 263, had come to the country.
