Fingerprints are unique to each individual and have been used to determine identity since the late 19th century. Despite being overlooked for centuries, the Quran emphasizes the importance of fingerprints, which has only been fully understood in modern times. Fingerprints remain unchanged throughout a lifetime, making them an effective and reliable source of identification. Therefore, fingerprints are an important factor in verifying identity.
