A summary of speech by Ja’far ibn Abī Tālib in the court of Abyssinia (today Ethiopia) in answer to the questions posed by the Christian king.
After the conversion of many prominent Meccans to Islam, the companions of Muhammad began to offer prayers publicly in 613. In turn, the Quraysh intensified their opposition by torturing the Muslims. Muhammad told his followers to leave for Ethiopia, where “a king rules without injustice, a land of truthfulness—until God leads us to a way out of our difficulty.”
The migration known as the first Hijarat was made in two groups totalling more than a hundred persons. According to Islamic tradition, eleven male and five female Sahabah, the Muslims who originally converged in Mecca, sought refuge from Quraysh persecution in the Kingdom of Aksum (modern-day Ethiopia) in seventh Islamic month (Rajab) of 7 BH (614–615 CE) in the first batch. Later on, a bigger group of eighty-three men and eighteen women emigrated (separately). This is called the second emigration. This group was headed by Ja’far ibn Abī Tālib—the son of Abu Talib ibn ‘Abdul Muttalib (the uncle of the Islamic prophet Muhammad)—who was the only person from the Banu Hashim clan who migrated to Abyssinia. Abyssinia at that time was ruled by a Christian King, Aṣḥama ibn Abjar, or King Armah locally, famous for his mercy and equity. — Wiki
