I do not know if sister GS is still here, apologies sis I will respond for now and you can add if you wish later:
Claire no worries it is good to understand someone with a different perspective thanks for inquiring:
"Whenever a person commits a sin, he alone is responsible for that sin. Every person is responsible for his or her own actions. Consequently, no human being who has ever lived is responsible for the mistakes made by Adam and Eve. God says in the Quran:
“And no bearer of burdens shall bear another’s burden.” (Quran 35:18)
Adam and Eve made a mistake, they repented sincerely, and God in His infinite wisdom forgave them. Humankind is not doomed to be punished, generation after generation. The sins of the father are not visited upon the sons.
“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)
Above all Islam teaches us that God is the most forgiving, and will go on forgiving, repeatedly. Part of being human is making mistakes. Sometimes the mistakes are made without deliberation or a bad intention, but sometimes we knowingly and deliberately sin and do wrong to others. Therefore as human beings, we are constantly in need of forgiveness.
The life of this world is fraught with trials and tribulations, however God did not abandon humankind to theses tests. God equipped humankind with an intellect and the ability to make choices and decisions. God also gave us words of guidance. As our creator, He is well aware of our nature and eager to guide us on the straight path that leads to eternal bliss.
The Quran is God’s final revelation and it is applicable for all of humankind; all people, all places, all times. Throughout the Quran God continually asks us to turn to Him in repentance and ask for His forgiveness. This is the road to salvation. This is our rescue from destruction.
“And whoever does evil or wrongs himself but afterwards seeks God’s forgiveness, he will find God Oft Forgiving, Most Merciful.” (Quran 4:10)
“And O my people! Ask forgiveness of your Lord and then repent to Him, He will send you (from the sky) abundant rain, and add strength to your strength, so do not turn away as criminals, disbelievers in the Oneness of God.” (Quran 11:52)
“Say: ‘O My slaves who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of God, indeed God forgives all sins. Truly, He is Oft-Forgiving, Most Merciful.’” (Quran 39:53)
Quran is not only a book of guidance, it is a book of hope. In it God’s love, mercy, and forgiveness are obvious and thus humankind is reminded not to give in to despair. No matter what sins a person may have committed if he resolutely turns to God, seeking forgiveness his salvation is assured.
Prophet Muhammad described sin as black spots covering the heart. He said, “Indeed if a believer sins, a black spot covers his heart. If he repents, stops the sin, and seeks forgiveness for it, his heart becomes clean again. If he persists (instead of repenting), it increases until it covers his heart…”
Salvation in Islam is not required because of the stain of original sin. Salvation is required because humankind is imperfect and in need of God’s forgiveness and love. In order to understand the concept of salvation correctly we must understand other topics embedded in salvation. These are, understanding the importance of tawheed, or the Oneness of God, and knowing how to repent sincerely ."
