Much has been said about the Terrorist muslims.
This is not acceptible.
I would like to reiterate that Muslims are not allowed to take their own lives nor anyone elses.

Quran 4:29-30

004.029
YUSUFALI: O ye who believe! Eat not up your property among yourselves in vanities: But let there be amongst you Traffic and trade by mutual good-will: Nor kill (or destroy) yourselves: for verily Allah hath been to you Most Merciful!
PICKTHAL: O ye who believe! Squander not your wealth among yourselves in vanity, except it be a trade by mutual consent, and kill not one another. Lo! Allah is ever Merciful unto you.
SHAKIR: O you who believe! do not devour your property among yourselves falsely, except that it be trading by your mutual consent; and do not kill your people; surely Allah is Merciful to you.

004.030
YUSUFALI: If any do that in rancour and injustice,- soon shall We cast them into the Fire: And easy it is for Allah.
PICKTHAL: Whoso doeth that through aggression and injustice, we shall cast him into Fire, and that is ever easy for Allah.
SHAKIR: And whoever does this aggressively and unjustly, We will soon cast him into fire; and this is easy to Allah.

Those that kill innocent people, specially the old, women and Children in ANY way is not supposed to be called muslims!
They are Khafir!
