Yawm al-Qiyamah, or the Day of Judgment, is a significant concept in Islam. It is believed to be the day when all individuals will be resurrected and held accountable for their actions during their lifetime. This event marks the end of the world and the beginning of eternal life in either paradise or hell. On Yawm al-Qiyamah, every person will be judged by Allah based on their deeds, intentions, and faith. The righteous will be rewarded with eternal bliss in Jannah (paradise), while those who have sinned without repentance may face punishment in Jahannam (hell). This day emphasizes the importance of moral conduct and faith in Islam.
