In the time of Jesus the Samaritans where people who had taken the scriptures that existed at the time and had added four Gods on top of them. Do you know who else took the scriptures and added something on top of it? Mohamed did.
It is as if he said in 2015 USA, a Christian man was traveling to a town and on the road he was robbed and Muslim man came along and bought him clothes and put him up at a hotel.
At the end of the story Jesus says go and do likewise. I think that he means even those who hate you are your neighbors and should be treated like the good Samaritan treated that man!
We should have sympathy for our Muslim neighbors and try to win them over with our good deeds.
