I read Christopher McDougall's book 'Born to Run.' If running were a religion this would be its bible. I actually scribbled my favorite passages on my arm to read during the race.
This is the beauty of the Qur'an: it asks you to reflect and reason and not to worship the sun or moon but the One who has created everything. The Qur'an asks man to reflect upon the sun and moon and God's creation in general.
