38-Surah Sad ( The Letter Sad ) 2
Quran's Tafhim ( explanation)
*3) If the interpretation given of suad by Ibn 'Abbas and Dahhak is accepted, the sentence would mean this: "By this noble Qur'an, or by this Qur'an which is full of admonition, Muhammad (upon whom be Allah's peace) is presenting the Truth, but the people who persist in their denial, are in fact, involved in arrogance and stubbornness." And if suad is taken as one of those enigmatic letters whose meaning cannot be determined, then the answer to the oath is omitted, which is indicated by "but" and the sentence following it. The meaning then would be: "The reason for the denial of these disbelievers is not that the religion which is being presented before them is unsound, or that Muhammad (upon whom be Allah's peace) has shown some slackness in the matter of presenting the Truth before them, but their own boasting and bragging, their haughtiness and stubbornness, and this is borne out by this Qur'an itself, which is full of admonition. Every unbiased person who studies it will admit that fill justice has been done in it to the task of making the people understand the Truth. "
