Islam rejects the Christian concept of original sin and the notion that all humans are born sinners due to the actions of Adam. God says in the Quran:
“And no bearer of burdens shall bear another’s burden.” (Quran 35:18)
Every human being is responsible for his or her actions and is born pure and free from sin. Adam and Eve committed a mistake, they repented sincerely and God in His infinite wisdom forgave them.
“Then they both ate of that tree, and so their private parts appeared to them, and they began to stick on themselves the leaves from Paradise for their covering. Thus did Adam disobey his Lord, so he went astray. Then his Lord chose him, and turned to him with forgiveness and gave him guidance.” (Quran 20:121-122)
