One sentence that throws the problem of evil out of the window.

[WinterHold]

Catholic Lady, I don't like to say it in anybody's face; but according to Islam you are in HELL for worshiping Jesus; the only slack is that I'm not God and God does what he wants

Sura 5, The Quran:
( 17 )   They have certainly disbelieved who say that Allah is Christ, the son of Mary. Say, "Then who could prevent Allah at all if He had intended to destroy Christ, the son of Mary, or his mother or everyone on the earth?" And to Allah belongs the dominion of the heavens and the earth and whatever is between them. He creates what He wills, and Allah is over all things competent.

And

Sura 3, The Quran:
( 84 )   Say, "We have believed in Allah and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him."
( 85 )   And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.

He didn't tell you about these two verses?
I find it quite ironic for a Muslim to form a missionary alliance when a command was already given in the Quran not to do it:

Sura 5, The Quran:
( 51 )   O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you - then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people.
( 52 )   So you see those in whose hearts is disease hastening into [association with] them, saying, "We are afraid a misfortune may strike us." But perhaps Allah will bring conquest or a decision from Him, and they will become, over what they have been concealing within themselves, regretful.
( 53 )   And those who believe will say, "Are these the ones who swore by Allah their strongest oaths that indeed they were with you?" Their deeds have become worthless, and they have become losers.

So I'm not being mean to a troll, whom I know knows about all of this, but keep it a secret to get more supporters for his missionary effort.
Personally; I hate and despise being lied on. Or used like a puppet. This is the book. Take it or leave it.

Yep and this:

Sura 3, The Quran:

( 85 )   And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
