Miracle and challenge

This writing wants to reject the claim of persons that they have supposed miracle is dependent upon challenge. Several examples and certain reasons indicate the prophet’s morality is sign of his veracity and his miracle after Quran and before thousands sensible and palpable miracles. Quran has nominated the prophets’ miracle sign and nowhere has brought restriction of challenge. Quran is the only miracle that is with challenge. Our great ones haven’t used challenge in definition of miracle.
