Migration to Abyssinia
In regards to the migration to Abyssinia, Hazrat Mirza Bashir Ahmad (ra) states in Sirat Khatamun-Nabiyyin:
“Therefore, upon the instruction of the Holy Prophet (sa), in the month of Rajab 5 Nabawi, eleven men and four women migrated to Abyssinia.”
Hazrat Mus‘ab (ra) bin Umair was among them. Hazrat Mirza Bashir Ahmad (ra) further writes:
“It is very strange that a majority of these pioneer immigrants were those who belonged to powerful tribes of the Quraish, and the weaker were few and far between. This illustrates two things: firstly, even those who belonged to the powerful tribes of the Quraish were not safe from the cruelties of the Quraish. Secondly, weak people such as slaves etc. at that time were in such a grave state of weakness and misery that they were not even able to migrate … Nonetheless, when the Quraish were informed of this, they were deeply enraged that this ‘prey’ had slipped their hands. Hence, they pursued these immigrants, but when their men reached the coast, the ship had already departed and for this reason, they returned disappointed. Upon reaching Abyssinia, the Muslims found a life of great peace and protection from the cruelties of the Quraish after much difficulty and prayers.”
