Prof. Masudul Hasan has written the biographies of all the four rightly guided Caliphs. His approach has been scientific and objective. He expressed the facts and events as they happened.
This biography of Hadrat Ali Murtada (R.A) shows, in lime light, his life and his achievements which were either coloured or exaggerated by other authors.
Hadrat Ali's true greatness which is of a different type, has been dealt with, in all dimensions with great accuracy, suppressing no facts, about his life.
The Caliphate issue is also discussed at length, According to the author this issue was a political one. It was made a religious issue later on. In fact, Hadrat Ali (R.A) himself in his writings "Nahjul Balagha" expressed only his unhappiness in being passed over in the election of the Caliph. He did not blame anybody. Other matters like battle of Siffin and revolt of Kharijites have also been discussed objectively. In short, this book fills up the blanks left by the other authors in their writings to make it a perfect biography.
