Concept:The migration caused by persecution in the 5th year of Muhammad's (SAW) mission was the first Hijrah to Abyssinia.
Explanation:The Quraysh intensified their persecution of the early Muslims in Makkah.
In the 5th year of his mission, the Prophet (SAW) advised a group of Muslims to migrate to Abyssinia.
This was because the Negus, the ruler of Abyssinia, was known to be just and fair.
It was not the migration to Madinah, which occurred later in the 13th year of the mission.
Therefore, the destination of the migration due to persecution in the 5th year was Abyssinia.
Answer:A. Abyssinia
