The conflict between rationality and devotion is rooted from an inappropriate comprehension about status of reason in epistemic system of religion and also being unfamiliar with pure and vital educations. Although some of the educations from the Divine Book have devotional prospects and are out of the reach of conventional reason, pondering in verses indicates that this does not mean digressing from reason and devotion. Epistemic geometry of Hujurat Surah which involves religious lifestyle and etiquette is a multi-dimensional pyramid, from which one dimension takes a look at the behavior of God's servants, another dimension takes a look at the followers' behavior with Gods' Prophet (p.b.u.h) and the other dimension looks upon the behavior of faithful people with each other. The thing that is glowing on the peak of this pyramid is rationality of its propositions and leading the audience toward devotion. Reflecting on simple substances, contents and style of the Surah along with style of speech, the present article shows that how these verses, on the one hand, have rational propositions and on the other hand, how they provide the ground for human reason to achieve the truth, assistance, and then, to develop them. Arguing sentences, tangible metaphor, credit provisions, change of addresses, and conceptual boundaries are the methods of providing this ground.
