How can the specious argument be refuted that the miracles of the Holy Quran are similar to the miracle of the creation of man in previous scriptures, and what is the way to get rid of religious whisperings?

The Noble Quran came as a confirmer and an overseer of previous scriptures. This means that whatever the Quran attests to as true is accepted, and whatever it attests to as false is rejected, as it has been corrupted. The facets of the Quran's inimitability are many and varied, increasing a believer's certainty that it is the word of Allah and cannot be from anyone else. To gain knowledge and increase certainty, it is advisable to read reliable books in the field of scientific inimitability in the Quran and Sunnah (definition). Transient, unsettled doubt is treated like a whisper (waswasah) and does not affect one's faith.
