In Surah Al-Qiyamah (75:3-4), the Quran declares: "Does man think that We will never assemble his bones? Yes, [We are] Able to perfect his fingertips."
This verse refers to Allah's ability to reconstruct the fingertips, a part of the body whose absolute uniqueness in each individual was only discovered by science at the end of the 19th century.
In 1892, Sir Francis Galton scientifically demonstrated that fingerprints are unique to each individual and never change throughout life. This discovery founded dactyloscopy, the science of identification through fingerprints.
The papillary ridges that form fingerprints develop in the fetus between the 10th and 24th weeks of gestation, and their configuration is determined by genetic and environmental factors unique to each individual.
Even identical twins, who share the same DNA, have different fingerprints. No human being in history, nor in the future, has or will have the same fingerprints as another.
The Quran's choice to specifically mention the fingertips as an example of Allah's creative power is remarkable, because it is precisely this part of the body that has become the most reliable means of human identification.
