I dedicate this work sincerely to my parents, Zahra and Abolfazl, who did not spare any effort to help me succeed.
I also thank my husband, Ar-Ridha’ Muhammad Husayni, who provided encouragement and help in all stages of my work.
I appreciate the valuable assistance of Mr. Ruin Naddaf in reviewing and editing this translation.
It is my earnest wish that this book would serve as a good reference for clarifying Islam's perspectives towards different issues in this world and the hereafter.
All success comes from Allah (S.w.T.).
