As a Muslim, you firmly believe in the existence of these places based on the teachings of Islam. The concept of heaven and hell is a fundamental part of our faith, with Quranic verses and Hadiths supporting their existence. On the Day of Judgement, our actions will determine our fate in the afterlife, whether we will be rewarded with paradise or punished in hell. The belief in karma also influences our future, as our deeds, whether good or bad, will have consequences. Immortality and chastity play a role in shaping our lifestyles, affecting our moral values and behaviors towards others. It is important to uphold these principles to maintain a harmonious society.
