Abū 'Ubaidah ibn al-Jarrāḥ, was one of the ten companions of the Prophet Muhammad who were promised Paradise. He remained commander of a large section of Muslim armies during the time of Caliph 'Umar ibn al-Khattab and was on the list of 'Umar’s appointed successors to the Caliphate. The Brotherhood was made b/w him and Sa'd bin Mua'dh (or some say Salim Client of Abu Hudhayfa).

The Prophet (saas) publicly named ten men who would be guaranteed Paradise in the Hereafter. One of these fortunate men was Abu ‘Ubaidah bin Al-Jarrah. He was one of the earliest to accept Islam in its early days in Mecca. He took part in the migrations to Ethiopia and Medina for the sake of preserving his faith. He fought in all the major battles of Islam and spent most of his life as a soldier for Allah’s cause. He even killed his own father in battle when his father vowed to slay him for accepting Islam. Praising his character, the Prophet (saas) said: “Every Ummah has a trustworthy man; Abu ‘Ubaidah is the trustworthy man of this Ummah“.
