Is frog halal in Islam

Prophet Mohammad (Peace be upon him) forbade the killing of the frog, that why Muslims don't eat Frogs.

As for Pigs, it's not halal, because it was forbidden to eat in the holy Quran just like blood and dead flesh, and any meat that was not slaughtered In the name of Allah.

If it is necessary however, muslims are permitted to eat what would be considered non-halal meat e.g. in situations of starvation and near death.
