[Machine] He made a double-edged dagger for him, and when he grew up, he struck him on his shoulder, then struck him in another place, and then struck him in his waist, and 'Umar fell. It has been narrated in the authentic Hadith from Husain from 'Amr ibn Maymun in the story of the killing of 'Umar. When he stabbed him, the dagger flew with the knife with two edges that would not pass by anyone on the right or left except that it stabbed him. And in that, there is evidence that he was killed with a predetermined plan, then he was washed, shrouded, and prayed upon.
