What is the best admonitory word that can be included in a competition booklet for youth in the hospital, not exceeding one page?

Hearts harden, souls are distracted, and minds become oblivious. Therefore, there must be a preacher, and the best preacher is the remembrance of death and the departure from this life to the abode of recompense. Death exposes the true nature of this world and leaves no intelligent person joyful in it. Death comes suddenly, transforming a person into a lifeless corpse to be buried in the earth. It was narrated from the Prophet, peace and blessings be upon him, that he said: "The people who remember death the most, and who are most prepared for it, those are the intelligent ones. They have attained the honor of this world and the dignity of the Hereafter." Death is a door through which a person enters either into bliss or into Hellfire. So, the intelligent person must prepare for those moments.
