Long ago when there was nothing, Allah (god) created everything, the universe, the world, and our planet Earth. Allah the Almighty snapped his fingers and said, “Be” that was how the world was created.
Later, Allah (S.W) created man with dust and clay and then named him Adam (A.S); Allah had given Adam all the knowledge that Allah had known and placed him in the heavens. Adam (A.S) later on started to become lonely and then Allah thought, “let me make a partner, friend for Adam (A.S). So Allah (god) took Adam (A.S) left rib and then created Hawa (A.S) [Eve] and then told them what ever you do not eat from a certain tree.
Then the Shaytan (Satan) had whispered into Adam (A.S) and Hawa (A.S) because “he had vowed that every human being that is created I would corrupt them!” He whispered, “Go, Go eat from the tree and it will make as strong as Allah (S.W) they ate from the tree and nothing was happening.
Well, as you would know, Allah had found out because he is the creator and not the created and Adam (A.S) and Hawa (A.S) got kicked out of heaven and sent down to Earth, the first thing they did in Earth was to go to the bathroom. Allah said “if you want to come back to heaven you must worship me at Earth until your death and then you may go to heaven again!” Adam (A.S) and Hawa (A.S) did what they were told, and had many sons/daughtes and after their death they might’ve went to heaven.
