“One day after the Prophet (a.s) had said the morning congregational prayer in the mosque, he saw a slim, drowsy young man in the mosque. He was pale, skinny with eyes sinking deep into his face, and his skin loosely attached to his bones. He told him: “O' Harith! How did you get through the night?” He replied: “O' Prophet of God! I passed the night with certitude.” The Prophet was surprised and said: “There is a sign for certitude. What is the sign of your certitude? “ He replied: “O' Prophet of God! The sign of my certitude is that I am sad and sleepless. I suffer from thirst in the day. I have turned away from the world and everything in it. This has gone so far that I can see my Lord's Throne set up for Reckoning. All the people have been resurrected for Reckoning, and I am amongst them and can see the residents of Heaven filled with blessings; and resting on sofas; and getting to know each other. And I see the residents of Hell being tortured in fire and crying out. It is as if right now I can hear the roaring sound of the blazing fire of Hell.” The Prophet (a.s) turned to the other people and said: “This is a man whose heart is filled with the light of faith.” He then turned to that young man and said: “Be steadfast.” The man said: “O' Prophet of God! Please ask God to honor me to accompany you in some of the wars and get martyred.” The Prophet (a.s) prayed for him, and not long after that, they went to fight in a battle and he was the tenth man to be martyred in that battle.”
