In their outward appearance, hypocrites are almost no different from Muslims. Their intentions, however, is entirely different. To one considering their outward appearance, hypocrites could give the impression of being a pious person; with their speech, behavior and other traits, they impersonate believers and in their manner of worship, pretend conformity to religious norms.
However, their understanding of the religion is a product of their errant rationale, rather than of the Qur'an. The basis of their perspective on religion is their ambition to reap personal benefits, and satisfy their own desires and intentions.
In concealing these intentions, hypocrites strive to take advantage of those benefits that emerge from the positive environment fostered among believers who live by the morality of the Qur'an. They seek to profit personally from this bounty, abundance, beauty, peace, security, joy, unity, compassion, love and respect Allah has granted the believers as blessings. However, they believe none recognizes their opportunism but that they can readily deceive the believers. Moreover, they believe they are successful, a good fortune they attribute to their intelligence.
However, though they think otherwise, hypocrites are truly deluded. For, to the true believer, even the slightest insincerity is apparent. Still, beyond that, Allah, Who is aware of the innermost thoughts, knows the real intentions of these people. Consequently, those attributes of a believer they pretend outwardly have no validity whatsoever in Allah's sight.
Allah relates this truth in the following verse, "... What they are doing [their worship] is purposeless." (Surat al-Araf, 139) Moreover, Allah knows of the hypocrites' disingenuousness, and whatever else they think are able to conceal. Consequently, in the words of the Qur'an, through such insincerity, "... [hypocrites] deceive no one but themselves but they are not aware of it." (Surat al-Baqara, 9)
