On this matter @harrydre you are right, for there is such a thing as a bad Muslim. In fact, you will note more muslim terrorists:
* observe the Five Pillars of Islam, declaration of faith (shahadah), daily prayers (salat), fasting (sawm), almsgiving (zakat), and the pilgrimage to Mecca (hajj)
* fit the earlier bill used to declare old testament prophets as Muslim
http://www.wazua.co.ke/forum.as...&m=541732#post541732Many Muslims place very strict conditions before a sentence of takfir (declaring another Muslim as non believer):
alim must pronounce fatwa, some say the prophet, or the ummah (community) etc.
Thus...
what is common among the world leading terror groups Al Qaeda, Taliban, Al shabaab & Boko haram, .....is that they're fanatical adherents of the Muslim faith; who must Istighfaar (seek forgiveness) of Allah for the sins committed and turn repentant unto Allah.
And for my Muslim neighbor, a duty towards their brethren
