The five.

From the aspect that they are for the guidance of the human species

and its direction,

is a proof in itself that this speech is sent down from the presence of Allah, the All-Wise, the All-Knowing.

Just as a skillful doctor, if he looked, for example, at the Canon (of Ibn Sina)

and meditated upon its explanation of the causes of diseases, their signs, and its description of their medicines and treatment,

the least doubt would not befall him that the author of this book is from among the greatest skillful doctors in the craft of medicine.

Likewise, the one knowledgeable in the secrets of the divine laws who knows what things can be taught and imparted to people to refine their souls and reform their hearts,

then meditates upon these five sciences which the Wise Quran has comprised,

he would know with absolute certainty that these sciences have come with their meanings and demands in the Quran in a manner than which no better, lower, or more beautiful can be imagined.

And in any case,

the radiant sun is a proof from itself for itself,

so if you are in need of the proof

then do not turn your face away from it.
