First pledge of Aqabah

The next year, five of the six men from Yathrib returned to meet the Prophet during Hajj. They brought with them five converts from their own tribe and two from the tribe of Aus. The names of the five converts of the Khazraj were Mu’adh bin Harith (Mu’adh bin Ifra’a), Zakwan bin Abdul Qays, Ubada bin Samit, Yazeed bin Thulba, and Abbas bin Ubada bin Fadhla. The two men from the Aus tribe were Abul Haytham bin Al-Tayhan and Uwaym bin Sa’eda.

Again they met the Prophet in Mina, where he taught them more about Islam and asked them to make an oath of allegiance. This was known as the First Pledge of Aqabah. Specifically, it was a pact between the men and Allah that they would not associate any partners with Allah, commit theft, fornicate, kill their children, vilify others, nor disobey the Prophet when he instructed them to do good. Whoever fulfilled this pledge would receive his reward from Allah, and whoever violated any part of it and was proven guilty would be punished in this world as an atonement. If, however, someone broke the pledge and Allah hid his sin from people, that person would be dealt with by Allah, Who would either forgive him or punish him.
