Following the migration and return of the most Sahabas from the first migration to Abyssinia (Sa'd ibn abi Waqqas and some did not return but left Abyssinia by sea for preaching overseas to east Asia), the Muslims continued to suffer Persecution by the Meccans. This time, in 6 BH (615 CE) almost one hundred Muslims made a second migration back to Ethiopia where they stayed protected. After the Muslims in Arabia had migrated to Medina in AH 7 (628/629) and attained security, the Muslims in Ethiopia migrated back to Arabia and reunited with them in Medina after six years absence.
