Islam and faith, and a tear with great spiritual support. Therefore, these waves worked to liberate the semi-Arab African regions that were particularly subject to foreign influence, especially North Africa, which was under Byzantine influence.

Thus, the appearance of the light of peace was the beginning of a new chapter in the history of Arab migrations to Sudan and in the history of relations between Arabs and Sudan, as the Muslim Arabs had played a positive role in these relations.

And then the first migration of Muslims occurred when the early Muslims were subjected to the persecution of Quraysh, which prompted the Messenger of Allah, peace be upon him, to consider the migration of his companions to Abyssinia, and so Ja'far ibn Abi Talib and his companions left, and then some Arabs spread to Sudan.

And in the era of Umar ibn al-Khattab, may Allah be pleased with him, after Sham was liberated from Byzantine rule and before Amr ibn al-As entered Egypt, the Arabs of Ghassan, Khadam, and Amilah were in northern Sinai. Nevertheless, we see the connection of Egypt with the Arabian Peninsula before Islam and the resulting Arabization of the Egyptian people in terms of lineage and the subsequent Arab influences in various fields, especially in the ancient Egyptian language, which influenced the languages of the ancient Nadwa.

This perhaps explains the quick response of the Arab Egyptian people to the Arab Islamic movement. This is because, with the rapid spread of Islam, the friendly relations that linked Egypt with the Arabs continued, to the extent that the ruler of Egypt, al-Muqawqis, sent a gift to the Messenger of Allah, peace be upon him, in response to the Messenger's letter inviting al-Muqawqis to Islam. Likewise, some Egyptians embraced Islam before Amr ibn al-As succeeded in liberating Egypt from Byzantine rule in 20 AH / 641 AD.
