In 23 A.H., when Umar returned to Medina from Hajj;, he raised his hands and prayed,

"O God! I am advanced in years, my bones are weary, my powers are declining, and the people for whom I am responsible have spread far and wide. Summon me back to Thyself, my lord!" Some time later, when 'Umar went to the mosque to lead a prayer, a Magian named Abu Lulu Feroze, who had a grudge against 'Umar on a personal matter, attacked him with a dagger and stabbed him several times. Umar reeled and fell to the ground. When he learned that the assassin was a Magian, he sid, "Thank God he is not a Muslim."

'Umar died in the first week of Muharram, 24 A.H., and was buried by the side of the Holy Prophet (peace be on him).
