This book is the first in the series. It deals with sickness, which continues to afflict human beings from birth until death. Sickness strikes as light as a simple cold or allergy, and as hard as a plague or cancer. It keeps the human being under check, reminding him of his weakness and giving him a chance to turn to the One who possesses to afflict and cure. This book deals with sickness, its regulations, and lessons associated with it. It presents the Islamic stand toward a number of modern medical issues, and also discusses important regulations relating to those with disabilities.
