UMAR (radiallaahu anhu) became unconscious after he was stabbed, and it was said: “Nothing would wake him up except the call to prayer, if he is still alive.” They said to him, “The prayer has finished, O Leader of the Believers!” He woke up and said, “The prayer, by Allah! Verily, there is no share in Islaam for whoever abandons the prayer.” He performed the prayer while his wound was bleeding.
