1. The Recitation Trap:
Surah 2:44 shames 7th-century Jews for violating the very scripture they were currently reading. By appealing to their active text as the standard for "righteousness" and "reason," the Quran explicitly validates the authority of the 7th-century Old Testament.
2. The Logical Implosion:
This creates an inescapable dilemma. If the text they read was authoritative, the Quran affirms a scripture that directly contradicts it on foundational theology (like sacrificial atonement). If that scripture was already corrupted, the Quran is guilty of using a corrupted lie as a divine standard for righteousness.
This verse identifies the location and timing of those scriptures. This is a addressing the Jews in 7th-century CE Medina using their current book to shame them about their current behaviour. The scripture of the Jews was the Torah according to the Quran (known in Arabic as the Taurat).
Surah 2:44:
"Do you order righteousness of the people and forget yourselves while you recite the Scripture? Then will you not reason?"
Premise A:
Surah 2:44 confirms the Jews were reading/reciting their Scripture in the 7th century.
Premise B:
Surah 2:44 confirms that this Scripture was an authoritative standard for "righteousness" and "reason."
Premise C:
The Scripture they were reading then is the same Scripture we possess now (the Old Testament). The Torah (First five books) being part of that scripture.
Conclusion:
Therefore, the Quran affirms at least the Torah. But the Torah contradicts the Quran such as:
If the Torah is true, the Quran is false. If the Torah is false, the Quran is false for affirming a false book.
