The concept of original sin is not recognized in Islam. Muslims believe that all people are born sinless with inclination toward truth.
Adam and Eve were forgiven by God.
فَأَقِمْ وَجْهَكَ لِلدِّينِ حَنِيفًا ۚ فِطْرَتَ اللَّهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا ۚ لَا تَبْدِيلَ لِخَلْقِ اللَّهِ ۚ ذَٰلِكَ الدِّينُ الْقَيِّمُ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ
So direct your face toward the religion, inclining to truth. [Adhere to] the fitrah of Allah upon which He has created [all] people. No change should there be in the creation of Allah . That is the correct religion, but most of the people do not know.
مُنِيبِينَ إِلَيْهِ وَاتَّقُوهُ وَأَقِيمُوا الصَّلَاةَ وَلَا تَكُونُوا مِنَ الْمُشْرِكِينَ
[Adhere to it], turning in repentance to Him, and fear Him and establish prayer and do not be of those who associate others with Allah
(The holy Qurʼān 30:30-31)
