Life in this world is fragile and inevitably comes to an end. When death arrives, a grave is dug and the physical body is buried. While the body rots, the soul that once inhabited the body is alive in an unseen world. That world of the unseen terrifies some souls, and welcomes others with open arms. According to the Koran, every living being has a soul. All souls have full perception, awareness, and sensation of things in both this world and the unseen one.
