re: Nonmuslims hugging Muslims [Eating with Muslim]
Well spoken Bhai. 
I have never had a problem hugging my comrades even after several hours of battering away at each other…:faris: :faris: we still hug to show that we have no hard feelings. 
As long as it’s between members of the same sex in a non sexual way then thats fine.
In my elders times close physical contact was reserved only for the best of friends… except on Eid day when everyone around is a friend…
Surely if hugging was haraam why did Nabi Kareem Salalho Alyhi Wassalam hug many Kafirs who were his good friends.
There are thousands of historical annecdotes of Muslims high and low that showed mutual respect even for enemies… Though no Historical proof exists that figures like Saladin Ayubi and Richard Cour De Lion ever met the attitudes of the period show that there was a deep understanding between the two.
Even recently if you go to the Indo Pak border and meet with some of the people there you will see many Pakistani’s hugging Indians and vice versa.
This is not so much as a religous thing as it is a human aspect of friendship, respect and general gestures of goodwill.
