Muslims also believe in eternal torment in hell. Didn't you know that? If you get to paint me with a wide brush, then I get to do the same to you. If you can assume that anyone who believes that the wages of sin is death is a JW, then I can assume that anyone who believes in eternal torment is a Muslim. The logic is the same, it's just that the shoe is on the other foot. How do you like it?
Matthew 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
42 For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
43 I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
44 Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
45 Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
46 And these shall go away into everlasting punishment: but the righteous into life eternal.
