Allah SWT said in Surah Al Qiyamah verses No. 3 & 4.

Does man think that We will not assemble his bones? Yes. [We are] Able [even] to proportion his fingertips.

Unbelievers argue regarding resurrection taking place after bones of dead people have disintegrated in the earth and how each individual would be identified on the Day of Judgement. Almighty Allah SWT answered that He can not only assemble our bones but can also reconstruct perfectly our very finguretips.

Why does the Qur'an while speaking about determination of the identity of the individual, speaking specifically about fingertips? In 1880, fingerprinting became the scientific method of identification, after research done by Sir Francis Golt. No two persons in the world can ever have exactly the same fingerprint pattern. That is the reason why police forces worldwide use fingerprints to identify the criminal.

1400 years ago, who could have known the uniqueness of each human's fingerprint? Surely it could have been none other than the Creator Himself!.
