Islam is the last of the monotheistic Abrahamic religions. It recognizes and respects its predecessors namely Judaism and Christianity. Jews and Christians have the honorary title of "the People of the Book," as fellow believers in the One God and the recipients of His Scriptures (Torah and Gospel). There are doctrinal differences within the unity of the Abrahamic faith.
The Arabic name of God is Allah (the word used even by Christian and Jewish Arabs), and God's attributes are His names. These include names, such as, The Forgiver, The Pardoner, The All-Forgiving, The Forbearing, The Acceptor of Repentance, The Merciful, The Compassionate and The Loving.
The Quran, the book that Muslims believe to be the very word of God conveyed to Muhammad, is in its original text word to word and letter to letter. It is replete with verses that emphasize the limitless forgiveness of God, urging the believers to exercise the virtue of forgiveness, and reminding them that proven forgivers are the first to deserve forgiveness.
