86. The Quran makes manifest everything on which depends guidance or deviation, success or failure. Whose knowledge is essential for following the right way. What clearly distinguishes truth from falsehood.
In this connection one should guard against that meaning of this sentence and the like in the Quran according to which some people interpret “everything” to mean the knowledge of all sciences, arts, etc. and in order to prove the correctness of their interpretation, they have to pervert the real meaning of the Quran.
87. This Book is a guidance for those who surrender to it as a divine Book and follow it in every aspect of life. Then it will bring Allah’s blessings upon them, and will give them the good news that they will come out successful in the court of Allah on the Day of Judgment. Or, the contrary, those people who reject it shall not only be deprived of guidance and blessing but will also find it as a testimony against themselves on the Day of Resurrection when Allah’s Messenger will stand up to testify against them. This Book will prove to be a strong argument against them. For Allah’s Messenger will say that he had conveyed its message which made manifest the distinction between truth and falsehood.
