The second pledge at al-ʿAqabah (Arabic: بيعة العقبة الثانية, romanized: bayʾa al-ʿaqaba al-thaniya) was an important event in Islam where 75 residents of the city of Medina pledged their loyalty to Muhammad as their leader in an oath of allegiance known as a bay'ah.
The pledge occurred in 622 CE at a mountain pass (al-ʿaqabah) five kilometers from Mecca.
Converts to Islam came from both non-Jewish tribes of Arabia present in Medina, such that by June of the subsequent year seventy-five Muslims came to Mecca for pilgrimage and to meet Muhammad.
The guarantee of protection led (orientalist)people who studied the language,culture,history or custom of countries in eastern asia and ulema to describe it as the "Pledge of War".
