The Migration to Abyssinia (Arabic: الهجرة إلى الحبشة‎ ‎ , "al-hijra ʾilā al-habaša"), also known as the First Hegira (Arabic: هِجْرَة‎ ‎ "hijrah"), was an episode in the early history of Islam, where Prophet Muhammad's first followers (the "Sahabah") fled from the persecution of the ruling Quraysh tribe of Mecca.
 They sought refuge in the Christian Kingdom of Aksum, present-day Ethiopia and Eritrea (formerly referred to as Abyssinia, a name derived from the Arabic "Al-Habash"), in 9 BH (613 CE) or 7 BH (615 CE) .
 The Aksumite monarch who received them is known in Islamic sources as the Negus (Arabic: نجاشي‎ ‎ "najāšī") "Ashama ibn Abjar".
 Modern historians have alternatively identified him with King Armah and Ella Tsaham.
 Some of the exiles returned to Mecca and made the hijra to Medina with Muhammad, while others remained in Abyssinia until they came to Medina in 628.

 Shunzei originally intended for Sadanaga to be his heir; however, he subsequently had two male offspring of his own, and Sadanaga was forced to step aside in favor of Fujiwara no Sadaie.
 As was common practice at the time, he became a monk, and acquired the religious name of Jakuren.
 Taking Saigyo as his model, he traveled around the country, composing poems of his travels.
 He was well regarded in his time and frequently associated with Fujiwara no Teika.
 He was one of the six compilers of the eighth imperial "waka" anthology, the famous "Shin Kokin Wakashū", and thirty-five of his poems were selected for the work.
 Before he died, he adopted Fujiwara no Ietaka, pupil to Shunzei.
 One of his poems was included in the famous poetry anthology "Hyakunin Isshu."
