A true Muslim cannot hurt a Christian (plus penganut agama lain juga macam Hindu, Buddha etc) in any way, neither by his hand nor by his tongue. Even Prophet Muhammad truly celebrated his Christian friends.
He even wrote to them.
"This is a message from Muhammad ibn Abdullah, as a covenant to those who adopt Christianity, near and far, we are with them. Verily I, the servants, the helpers and my followers defend them, because Christains are my citizens; and by Allah! I hold out against anything that displeases them. No one is to destrouly a house of their religion or to damage it. No one is to force them to travel and oblige them to fight. Muslims are to fight for them. If a female Christian is married to a Muslim it is not to take place without her approval and she cannot be prevent from going to her church to pray. Their churches are to be respected. No one of the nation (Muslims) to disobey the covenant till the Last Day."
A guide to all of us how to relate with our dear friends of other faiths. If Muslims actually follow what our beloved Prophet Muhammad told us to do we would be in such a better place and position than we are today.
