a very wrong and confused understanding of halal....
a cow/sheep not slaughtered properly is also haraam just as a pig is haraam.... it is only halal if slaughtered according to Islamic rites....
Agree with you about Diwan's coments, he really needs help in understanding all this Halal/Haram issue.
A certain live animal (permitted for Muslims to eat by Allah) can be called Halal but not Zabiha.
Zabiha is a meat of a Halal animal slaughtered according to the Islamic teachings.
And Allah knows best...
