Peace All,
One cannot claim to be a monotheist and commit atrocities. Because monotheism
is to believe in the one God. Now that belief in the one God is demonstrated
by certain moral behaviors, while certain moral behaviors demonstrate that one is
not a monotheist. Satan can go to the masjid under the guise of being muslim and
have all the appearances of being righteous, but his/her immoral behavior exposes
that person as not a monotheist but hypocrite or a kaffir.
You are what your conduct reveals. By the way monotheist are special i.e., Abraham, Moses, Jesus,
Muhammad, the saints, the righteous.
Peace and love to all:
Surely, those who believe, those who are Jewish,
the Christians, and the converts; anyone who
(1) believes in GOD, and
(2) believes in the Last Day, and
(3)
leads a righteous life,
will receive their recompense from their Lord;
they have nothing to fear, nor will they grieve.
