Since they believe that pork is bad and eating it is something that can get you sent to hell, then do they believe that I will be sent to hell for it?
That is the operative word, they believe. If they believe in God, then they should know what God said.
Matthew 15:10, 11
10 After Jesus called the crowd to Him, He said to them, “Hear and understand. 11 It is not what enters into the mouth that defiles the man, but what proceeds out of the mouth, this defiles the man.”*
Acts 10:10–15
10 But he became hungry and was desiring to eat; but while they were making preparations, he fell into a trance; 11 and he saw the sky opened up, and an object like a great sheet coming down, lowered by four corners to the ground, 12 and there were in it all kinds of four-footed animals and crawling creatures of the earth and birds of the air. 13 A voice came to him, “Get up, Peter, kill and eat!”14 But Peter said, “By no means, Lord, for I have never eaten anything unholy and unclean.” 15 Again a voice came to him a second time, “What God has cleansed, no longer consider unholy.”*
I guess I’m wondering if their rules extend to to others that aren’t their religion.
I can’t say, I am not into religions, but those of us with a relationship with God, can eat anything we want, because God had ordained that all living creatures on the face of the planet is fair game for man to eat; which means if I were in an area I can eat dogs, cats, and horses, it would be no different than cows, chickens, fish and deer.
Am i considered a sinner to them or is it just the people in their religion that eat pork who are condemned?
You would be considered a sinner to them, same as I, but for more reasons than eating pork. There are some Jewish sects that still do not eat pork, but they are no closer to being embraced by the Muslims.
