Umar Al-Faruq(رضي الله عنه) was so deeply interested in the outcomes of Qadissiyya battle that he used to go outside the gates of Madinah early in the morning, to see if he could, by chance, meet some messenger from the battlefield.
A messenger from Qadissiyya was about to enter Madinah, when Umar bin Al-Khattab (رضي الله عنه) stopped him and asked, “Where are you coming from, O young man?” The messenger replied, “From the field of Al-Qadisiyyah!” He did not recognize Caliph.
Consider the humility of Umar bin Al-Khattab that he did say not he was the Commander of the Believers. The bearer of the news was mounted on a she-camel, while Umar followed him on foot. Umar then asked him, “How is the situation in Al-Qadisiyyah? What is the outcome of the battle?” The messenger then told him the good news of the victory of the Muslims. Umar said to the messenger, “Just narrate the whole incident. How did the Muslims win?” The bearer of the news began to recount the detail while riding his she-camel. Unrecognized, Umar followed him quickly on foot, gleaning the outline of the battle. Entering Madinah, the people saluted Umar addressing him as the Commander of the Believers. It was only then the bearer of the news realized that he had been talking to Caliph Umar bin Al-Khattab(رضي الله عنه)himself.
Abashed, he cried out, “Why didn’t you tell me that you yourself are the Caliph?” The caliph replied simply, “It is well, my brother.”
Such was the unassuming manner of a man who, at that moment, was greater than both the Caesar and Chosroes.
