How can we advise young people who are immersed in worldly pleasures and heedless of preparing for the Day of Judgment?

Advice to the heedless youth is to repent before it is too late, for death comes suddenly. Disobedience has negative effects and its punishments are hastened in this world. Let them remember that the Prophet, peace and blessings be upon him, said concerning the seven whom Allah will shade: "And a youth who grew up in the worship of Allah." They must be ashamed before their Lord and take heed from the last verse revealed in the Qur'an: "And fear a Day when you will be returned to Allah. Then every soul will be compensated for what it earned, and they will not be wronged."
