“Death, from which you are running away from, will certainly catch up with you. Then you will be returned to the Knower of the Unseen and the Visible (i.e. Allah) and He will inform you about what you did.” Qur’an 62:8
Death is inevitable. Our purpose in life is to worship Allah alone, perform acts of righteousness and to avoid all that is forbidden. Our fate is being decided on the basis of our present actions, so we can either make use of our opportunities on Earth to ensure an eternal place for ourselves in Paradise, or we can waste them and condemn ourselves to eternal punishment in Hell.
