The Koran is very contradictory and not only IS there "Wiggle Room", but there is specific Sanction of one kind of Suicide.
Suicide Bombing (or other death) in the Cause of Islam.... "Martyrdom".
There is Nothing so Glorious in Islam in and indeed NOTHING else get's you and yours an Instant ticket to heaven.
So yes, jumping out the window from despair is forbidden, But it's Disingenuous and intentionally DECEIVING to say the acts We know as "suicide bombings" (homicide bombings, in which only 1 muslim, but 30 infidels are killed) are mere 'suicides' and are not allowed.
They are 'Martyrdoms' and CELEBRATED by Muslims.
Half the streets in Gaza named after people who committed "suicide"?
NO. It's called "Martyrdom" and Laila just tried to Snow you.
