Say hypothetically Im giving Dawah to someone. And I need to convince them that the day of judgement is true. Suppose that they already believe in a God who is Just. My argument was: We see that there exist mass murderers in this world, and doctors that save thousands of lifes, yet there ends are very similar. If Allah exists, then this cannot be a reality if this world was the end. Therefore Allah will judge us after we die. And because evil and good are not the same, We can deduce that those who are unjust and sinful in this dunya will be punished and of course, those who do good are rewarded. Then I made the statement that if you can't feel things in deep sleep, then what do you expect to feel punishment when you are dead? And hence, there is life after death. How can I better this arguement? if you have an alternative way of explaining it, im happy to know! (also if you dont, its totally fine, i just want to know)
