While it is stated in the Qur'an that it is easy for Allah to bring man back to life after death, peoples' fingerprints are particularly emphasized:
Yes, We are able to put together in perfect order the very tips of his fingers. (Quran, 75:4).
What is important is that this feature of fingerprints was only discovered in the late 19th century. Before then, people regarded fingerprints as ordinary curves without any specific importance or meaning. However in the Quran, Allah points to the fingertips, which did not attract anyone's attention at that time, and calls our attention to their importance. This importance has only been fully understood in our day. https://islamic-audio-book.com/miracles-of-the-quran-page/
