The doctrine of redemption in these traditions is strikingly similar. Both Islam and Christianity hold that humanity must be saved from sin, individual and corporate alike. Both traditions hold that corporate sin includes disrespect for human life, conflict, hatred, and intolerance.
While is is true that there's no "original sin" in Islam, the concept of atonement for sins, however, is an integral part of Islamic theology. It involves acknowledging the sin, feeling genuinely guilty about it, and sincerely turning to God for repentance, with the assurance in ones heart that God will forgive. If a fellow human is wronged, then he/she must be approached to make things right, together with sincerely seeking God's forgiveness. One has to be sincere in his/her intention not to commit the same sin again, but knowing at the same time, however, that God forgives again and again if the intention of repentance is sincere and that God's Mercy overwrites His wrath. The Islamic tradition is rich on this topic, with specific prayers and Quranic verses (and other devotional texts) which can be performed/recited whilst seeking God's forgiveness.
The idea of original sin is difficult to find in the Gospels, and appears an addition. It is certainly not within the Jesus-figure's expressed ideas. The Gospels take a far more intuitive, investigative approach to the matter with greater psychological depth.
