Allah is the creator, controller and sustainer of each and every phenomenon in the universe. A simple study of any creation would explain the existence of the unequalled power of the Creator behind it. Since human brain is incapable to deduce His characteristics, Allah should introduce Himself to us. The infallible sources we can rely for the knowledge about Allah are Quran and authentic Hadiths. These sources give a perfect description about Him and instruct man to pray solely to Allah, who is the only one worthy to be worshipped. This book is an attempt to understand Allah in the light of reliable divine revelations, Quran and authentic Hadiths.
