Asking, 'So when is the Day of Rising?' But when the eyesight is dazzled, and the moon is eclipsed, and the sun and moon are fused together, on that Day man will say, 'Where can I run?' No indeed! There will be no safe place. That Day the only resting place will be your Lord. That Day man will be told what he did and failed to do. (Qur'an, 75:6-13)
When the Great Event occurs, none will deny its occurrence. (Qur'an, 56:1-2)
