Is the Quran miraculous with regard to its linguistic eloquence only or is it in all fields?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

The Quran is a miracle in its wording, meaning, eloquence, rhetoric, structure, in the matters of the Unseen about which it informs us. It also give us information about the angels, humankind and the Jinn, and other miracles that are discovered every day. Many books about the miracles of the Quran were written in the past and in contemporary times, so for more details you may refer to them.

Allaah Knows best.
