Yes...and it ties in with hatred. Muslims hate infidels.
He needs to read a true translation of the Holy Koran.
Then he will know the source of the never ending hatred of infidels.
It is nothing personal, just the duty of true believing Muslims as spelled out in the Holy Koran.
The translations of the Holy Koran being sold to non Muslims have been altered to make Islam look like a religion of peace.
Every non Muslim (infidel) needs to read a true translation of the Holy Quran or Koran.
The print translations being sold in western nations have been significantly changed to make it look like Islam is a "religion of peace".
Then they might understand why this is happening and why it will never stop happening.
These true translations need to be required reading in high school and college.
Every Bible thumping Christian needs to read it to understand the Muslim world.
IMHO these are probably the most accurate translations, and they are FREE. https://www.gutenberg.org/ebooks/16955
