In the context of the skeptic's denial of bodily resurrection from scattered, decayed bones, the focus on fingertips emphasizes God's supreme power to reconstruct even the smallest, most delicate, and complex bones of the human hand. The Arabic word *banan* refers generally to the fingers/fingertips, not specifically the friction ridges. While a profound statement of divine capability, projecting modern forensic fingerprint matching onto a verse about skeletal reconstruction is anachronistic.
