The Quran does not bore people.

The verses of the Quran do not bore people but give pleasure even if they are repeated thousands of times.

How many times can you read a book that you like very much?3 times? 5 times? 10 times?

How many days on end can you eat a dish that you like very much?  3 days? 5 days? Or 10 days?

Yes, even the sweetest and most pleasant things bore people when they are repeated.

However, the Quran has such sweetness that repetition, which causes people to feel bored, increases the pleasure of the people whose hearts have not decayed and whose pleasure has not been destroyed when they read the Quran let alone making them bored; this fact is approved by everybody. Yes, the verses of the Quran do not make people feel bored even if they are repeated thousands of times; on the contrary, they give pleasure. 

A Muslim reads the chapter of al-Fatiha 40 times a day in prayers. He reads the same chapter 14.600 times a year and more than 1.000.000 times in his life. He reads it with excitement every time he reads it as if it has just been revealed and as if he is reading it for the first time.

No book other than the Quran has this property.

A book that has this exceptional property and that is read by millions of people at any moment cannot be the word of a human being by any means. No human word can be so effective. Then, the Quran is the word of Allah.
