Disbelievers Refuse to Accept the Completeness of the Quran [18:54] We have cited in this Quran every kind of example, but the human being is the most argumentative creature. [18:55] Nothing prevented the people from believing, when the guidance came to them, and from seeking the forgiveness of their Lord, except that they demanded to see the same (kind of miracles) as the previous generations, or challenged to see the retribution beforehand. [18:56] We only send the messengers as simply deliverers of good news, as well as warners. Those who disbelieve argue with falsehood to defeat the truth, and they take My proofs and warnings in vain.
