Africa was the second continent that Islam spread into, which explains why almost one-third of world Muslim population resides in this continent. Muslims crossed current Djibouti and Eritrea to seek refuge in current Ethiopia from Pagan Arabs. On the advice of Prophet Muhammad, in Rajab 8 BH, or May 614 AD, sixteen Muslims migrated to Abyssinia where they were protected by its king, an-Najashi, who has also accepted Islam later. They were followed by 101 Muslims later in the same year. By Muharram 7 H, or May 628 AD, all those Muslims returned to Medina, but locals who embraced Islam remained there.
