What term describes the pledge of allegiance given by the people of Madinah to the Prophet (PBUH) prior to the Hijra?

Explanation

– Bay’ah al-Aqabah refers to the pledges of allegiance given by representatives of Madinah at Aqabah, near Makkah, committing to support and protect the Prophet (PBUH), which paved the way for his eventual migration to the city.
– There were two such pledges, occurring in consecutive years prior to the Hijra.
– For exams, note that the second pledge involved a larger delegation and included a formal commitment to defend the Prophet as they would defend their own families.
