The book demonstrates a profound faith and learning, containing many relevant quotations from the Quran. Fazal doubted whether 'a democracy of western type' was capable of bringing about Islamic justice." He also acted as a muezzin for the local mosque in his old age, and established a school for girls, the "Sidra Model School", using the plot of rural land he was gifted after the 1954 Oval victory.
