The Quran is a reminder of the call to the Truth, but its full impact is felt only when the caller himself is fully dedicated to the cause of God, having sacrificed his own interests thereto. If he is to bring people to the right path, he must be seen to put others’ welfare before his own, even if this brings him toil and trouble. But no matter how perfect the presentation of the call to the Truth may be, only those will receive guidance from it who are capable of recognizing and appreciating the truth, and for whom the reasoned argument alone is enough to open their eyes. The August Being, who created the universe, has Himself revealed the Quran. Therefore, there is no contradiction between the Quran and nature. The Quran is a reminder of the truth. But its impact can only be commensurate with the ability —already innate in human nature—to recognise the truth.
