This, of course, a claim of belief on the part of those that believe Muslims. From my perspective the Quran is part of the universal progressive Revelation from God. Muslims would consider the Quran the only standard, The Christians would consider the Bible the only standard. and the Jews consider the Torah, Tanakh, and maybe Midrash the standard. The problem is 'Right, please?' only applies to Muslims in all these quotes in the absolute sense.
