The identity in the Fingerprint.
Allah says in the Quran:
Yes,we are able to put together in perfect order the very tops of his fingers. (Quran 75:3-4)

In this Ayah, the emphasis of the fingerprints has a very special meaning.This is because fingerprints are unique to every man.Everyone both living and dead has a unique Fingerprint.

But the importance of fingerprint was only discovered in the late 19th century.Before then people understood fingerprints has only curves with no importance r meaning.However Allah, points to the fingerprints , which did not attract attention at that time. Now the importance of fingerprint is known.
