Assalmu Alikum Dear Brothers and Sisters,
Please forward this verse of the Bible to your Christian friends. It rejects the notion, their core belief, about the so-assumed Original Sin.
Ezekiel 18:20 (Chapter 18 Verse 20)
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
