The Qur’an is the sacramental foundation of prayer in Islam. Its inspirational power is perpetually renewed through being recited and meditated upon by Muslims on a daily basis throughout their lives. This succinct and readable study offers unique contemporary insights into the spiritual, intellectual and moral interplay set in motion by the short Qur’anic chapters that are recited in their prayers by Muslims of all traditions, but which are particularly recommended within Shi’i Islam. Reza Shah-Kazemi engages closely and creatively with the Qur’anic chapters, basing his philosophical reflections on traditional exegetical principles, and focusing in particular on the relationship between the moral and the mystical aspects of the texts. The result is a stimulating meditation that probes the depths of meaning contained within the verses of a revelation by which the spiritual life of Muslims has for many centuries been nourished and fulfilled.
