A--- Disbelief contradicts Faith. Disbelief has different branches just as Faith does. We knew earlier that faith is basically a submissive belief that requires complete submission to deeds of obedience. So, disbelief is basically a kind of rejection and stubbornness that incurs arrogance and disobedience. Thereupon, all deeds of obedience are among the branches of belief; while all deeds of disobedience are among the branches of disbelief. Moreover, one should know that there are two types of disbelief: the Major Disbelief, which excludes one completely from the fold of Islam. This is the dogmatic disbelief that contradicts the utterance of the heart and its deeds or one of them. And, the Minor Disbelief, which does not exclude one from the fold of Islam. It only contradicts the perfection of belief. This is the so-called practical disbelief that contradicts neither the utterance of the heart, nor its deeds. It does not require or necessitate this as well.
