Beware on your weekend camping trips, you don't gather firewood on the wrong day...
"32 And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.
33 And they that found him gathering sticks brought him unto Moses and Aaron, and unto all the congregation.
34 And they put him in ward, because it was not declared what should be done to him.
35 And the Lord said unto Moses, The man shall be surely put to death: all the congregation shall stone him with stones without the camp.
36 And all the congregation brought him without the camp, and stoned him with stones, and he died; as the Lord commanded Moses."
--Numbers 15:32-36 (KJV)
But the point is:
Not all Muslims take everything literally and explicitly, just like not all Christians do.
Well first of all, that's Old Testament, not New Testament. The New Testament teaches against stoning people, and it is regarded by Christians as "The Revised Edition" of the Old Testament.
The Muslims have something similar, but reverse to this. All the parts about being kind and merciful and peaceful are in the first part of the Koran. All the stuff about killing infidels and destroying and murdering are in the later part of the Koran.
When they want to sell Islam as a religion of peace they point out the earlier versus, but Islamic clerics constantly teach that the later verses override the earlier verses.
One more thing. There are certain religious kooks in the Christian religion that do believe in all the fire and death stuff, but among Christianity, they are a tiny minority and considered an aberration.
For the Muslims, they are a significant plurality and are more or less mainstream in some Islamic countries.
