Muslims

OK. The Lord did make a covenant with Abraham that Ishmael's seed was going to be great; however, Abraham didn't give the priesthood to him. He gave it to Issac. From Adam to Jacob, the main office of God's priesthood was that of patriarch. Adam, Enoch, Noah, and Abraham administered the Lord's work, established covenants between God and the faithful, recorded their teachings and prophecies, and gave special priesthood blessings. A patriarch could bless his offspring by calling upon the powers of heaven. As he gave the birthright blessing to one of his sons, for instance, the keys and powers of the priesthood were extended to the next generation. In the patriarchal order, under the law of primogeniture, these priesthood rights normally were to be given to the eldest son; from Abraham to Ephraim the birthright blessing went to younger sons because of their righteousness (Gen. 21, 27-28, 48-49).

You mention that the Bible and the Koran are based on the Torah. You ask which one is correct. Of course we can't look at the original source because it has been lost thousands of years ago. If you look at the Muslim faith and the Koran, they believe in some or if not all the prophets of the Old and New Testament. Then, they say that Muhammad was the last prophet which God put on this Earth. I disagree with this kind of thinking because I know that we need prophets to tell us the will of God in these last days like in the times of old. Plus, they deny the divinity of the Savior which means that they don't believe that Jesus was the Son of God and died for our sins so we we may return to Heavenly Father. I totally disagree with that too. For the most part however, I do agree with Muslims in beliefs such as faith, prayer, fasting, repentance, compassion, modesty, and strong families as cornerstones of individual spirituality and community life.
