In this biographical chapter Qābel’s life is divided into three stages: the early revolutionary years; the middle years when he received his ejtehād from his spiritiul mentor, Ayatollah Montazeri; and his final years which witnessed his more mature thoughts over a range of social, political, and religious issues. The chapter is written by examining the ten e-books which were largely assembled after his death. The main features of his works are also highlighted.
