One of the ten Companions promised Paradise and the man the Prophet called 'the trustee of this nation.' He was supreme commander in the conquest of Syria and died in the plague of Amwas in 18 AH. His shrine is venerated at Deir Alla in the Jordan Valley; al-Harawi records three competing claimed tombs (Deir Alla, Tiberias, Baysan). (Sources: TDV İslam Ansiklopedisi 'Ebû Ubeyde b.
