The book explains that the objective of religious life should be to change this world, including the personality of the individual himself and extending to the whole of human society, so as to reconstruct it in accordance with the will of Allah as revealed in the Qur’an. The religion should be understood directly from the Qur’an aided by the Sunnah, and all human interpretations should be treated as secondary, tentative and, in principle, liable to error and open to correction.
