About The Book

The challenge of how to determine twilight prayer and fasting times at high latitudes is an issue that has vexed successive generations of Muslims since the community first began to dwell in northern lands. This work represents the most comprehensive, meticulous and balanced approach to the subject composed in any language.

The author has both demonstrated and collapsed the complexity of the subject by exploring it from the perspective of definitions, science, scripture and sacred law, as well as providing a literature survey of classical and modern attempts at observation, before presenting the results of his own systematic, scientifically-rigorous set of observations. 

As well as providing a comprehensive set of recommendations for the issue under discussion, this work sets a standard for works on modern legal issues in general.
