Persecution by the Quraish grew fiercer every day and the sufferings of the Prophet's disciples became unbearable. He had heard of the righteousness, tolerance, and hospitality of the neighboring Christian king of Abyssinia. He recommended such of his companions who were without protection to seek refuge in the kingdom of that pious king, Al Najashi (Negus). Some fifteen of the unprotected adherents of Islam promptly availed themselves of the advice and sailed to Abyssinia. Here they met with a very kind reception from the Negus. This is called the first hijrah (migration) in the history of Islam and occurred in the fifth year of the Prophet Muhammad's mission, A.D. 615. These emigrants were soon followed by many of their fellow sufferers, until the number reached eighty-three men and eighteen women.
