Keraunoparalysis is a temporary paralysis caused by lightning strike.
Lightning strikes can also induce a transient paralysis known as keraunoparalysis. Signs and symptoms of keraunoparalysis include lack of pulse, pallor or cyanosis, and motor and sensory loss in the extremities. However, keraunoparalysis usually resolves within a few hours.
A lightning strike can cause temporary paralysis. This was only known recently, however this was portrayed in the Quran 1400 years before it was discovered.
٤٤ فَعَتَوْا عَنْ أَمْرِ رَبِّهِمْ فَأَخَذَتْهُمُ الصَّاعِقَةُ وَهُمْ يَنْظُرُونَ
٤٥ فَمَا اسْتَطَاعُوا مِنْ قِيَامٍ وَمَا كَانُوا مُنْتَصِرِينَ
"They could not rise up" today we know why, this is temporary paralysis from the lightning strike.
How could an illiterate man who lived 1400 years ago have known about keraunoparalysis?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
