This verse forbids the very thing a Muslim must do to justify their Quran. They must raise the Bible to the same standard as the Quran.
Surah 2:136:
"Say, We believe in Allah and that which is revealed unto us and that which was revealed unto Abraham, and Ishmael, and Isaac, and Jacob, and the tribes, and that which Moses and Jesus received, and that which the prophets received from their Lord. We make no distinction between any of them, and unto Him we have surrendered."
The phrase "la nufarriqu bayna ahadin minhum" ("we make no distinction between any of them") is a logical guillotine.
If you make no distinction between the revelation of Jesus and the revelation of Muhammad, you CANNOT claim the Quran is the "final criterion" that overrules the Gospel.
If the Gospel says Jesus is the Son of God (John 3:16) and the Quran says He is not, the Muslim is forced to make a distinction.
If they choose the Quran's version, they violate 2:136.
If they accept both as equal, they are holding two contradictory "truths," which is a logical impossibility.
The verse commands belief in what the prophets received.
God would not command belief in something that is no longer available or has been corrupted into a lie.
If the Torah and Gospel were corrupted by the 7th century, God is commanding Muslims to believe in "corrupted" data.
If they were not corrupted, then the text we have today (which matches the 7th-century manuscripts) is the Word of God. And if that text is the Word of God, Islam is false because the Bible denies Muhammad's core message.
The Preservation of the "Received" Word
The verse commands belief in what the prophets received.
God would not command belief in something that is no longer available or has been corrupted into a lie.
If the Torah and Gospel were corrupted by the 7th century, God is commanding Muslims to believe in "corrupted" data. If they were not corrupted, then the text we have today (which matches the 7th-century manuscripts) is the Word of God. And if that text is the Word of God, Islam is false because the Bible denies Muhammad's core message.
The verse presents revelation as a single, consistent stream. This stream is defined by the Blood Covenant. From the "Tribes" to Jesus, the theme is sacrifice and atonement.
The Quran removes the sacrifice, the blood, and the deity of the Messiah. By doing so, it creates a "distinction" so vast that it effectively cuts itself off from the very prophetic line it claims to belong to.
This verse forces the Muslim to be a "Biblical Christian" in order to be a "True Muslim."
