Yes, Muslims believe in life after death. Belief in the afterlife is a fundamental tenet of Islamic faith. The Islamic understanding of the afterlife is based on the teachings of the Quran, the holy book of Islam, as well as the Hadiths, which are the sayings and actions of Prophet Muhammad(Peace be upon him).
According to Islamic belief, after death, individuals will be resurrected on the day of Judgement (Qiyamaah) and will be judged based on their deeds during their earthly lives. Depending on their actions, individuals will either be rewarded with eternal paradise (Jannah) or face punishment in hell (Jahannam). The concept of the afterlife is central to Islamic morality and serves as a motivation for adherents to lead righteous and ethical lives in accordance with Islamic teachings.
