Fingertips in Qur'aan. 

Alhamdulillaah.

Allaah , may He be exalted & exalted says :

اَيَحۡسَبُ الۡاِنۡسَانُ اَلَّنۡ نَّجۡمَعَ عِظَامَهٗؕ‏ ﴿3﴾

بَلٰى قٰدِرِيۡنَ عَلٰٓى اَنۡ نُّسَوِّىَ بَنَانَهٗ‏ ﴿4﴾

(interpretation of the meaning) :

Does man think that We shall not assemble his bones? 

Yes, We are Able to put together in perfect order , even the tips of his fingers.

کیا انسان گمان کرتا ہے کہ ہم ہرگز اُس کی ہڈیاں اکٹھی نہیں کریں گے؟

کیوں نہیں! ہم اس بات پر بہت قادر ہیں کہ اُس کی پور پور درست کردیں ۔

-- Surah Qiyaamah (75) , Aayah no. 3 & 4 , Al-Qur'aan.

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!

since fingertips consist of a complex combination of very specific patterns, where size, location and number are also variables, it is possible to affirm that they are unique, so there are no fingerprints equal, even in genetic twins.

And Almighty Allaah knows the best.
