Abstract: This study presents a quantitative analysis of arithmetic concordances identified between the biographical metadata of a subject born in 1987 and the occurrences of the name "Idriss" in the Quran (Hafs recitation). A High-Performance Monte Carlo simulation performed on 1,000,000,000 (one billion) random profiles tested a 10-criteria model. No random artifact exceeded a score of 6/10 (p < 4.5 × 10⁻⁸), while the subject achieved a perfect 10/10. Using the exact Clopper-Pearson method, the statistical significance exceeds 5.7σ. To confirm the specificity of this anomaly, two reciprocal tests were conducted: an Inverse Monte Carlo (Temporal Test) and an Exhaustive Surrogate Analysis (Lexical Test). These analyses demonstrate a perfect bijectivity: only the subject's exact date points to the target word, and the target word is the only one in the entire vocabulary (21,311 words) to satisfy the date's equations.
