As Salaamu Alaykum Wa Rahmatullahi Wa Barakatuhu all. And peace to everyone else.
Let me really make it very simple and clear without using those long and difficult words that are meant to defeat the truth and confuse the innocent.
The Soul is like the driver of the Car. The Car is the Material, call it whatever you want, chemicals, particles, atoms. At the end of the day, the body is the car and the Soul is the driver. Mind you, there is also a passenger called,"Devil," who's only objective is to steal(drinking, sinning, deception...etc) the car by fooling the driver and ultimately locking him in the trunk to take over the car in order to abuse it and crash it. But who is responsible at the end of the day? The owner of the car who was the human soul. How many times you had a friend as a passenger that desired to drive your beautiful car???
Now, a car must have a maker. And the maker must provide guidelines of how to maintain and use the car. To Muslims, this is Allah, who provided the Quran and Sunnah as guidelines on how to live this life in order to get the best of this World and the hereafter.
Now, if you deny that the body and soul does not have a maker or owner, is like saying the car does not have a maker or owner. If you do this, then, you are a criminal in the creation in the sight of the Creator! Reason? You denied the maker His rights and thus, you deserve a prison called, Hell.
Life is once, the truth is easy but doubt can destroy your future. Make a supplication to your Maker from a clean heart and you will understand the truth.
Wa Alaykumu Salaam Wa Rahmatullahi Wa Barakatuhu.
