The aritcle published by israeil reseaches is anti_arabic and biased. The creator ALMIGHTY say's

وَلَقَدْ يَسَّرْنَا الْقُرْآنَ لِلذِّكْرِ فَهَلْ مِنْ مُدَّكِرٍ ﴿القمر: ٤٠

And We have indeed made the Qur'an easy to understand and remember: then is there any that will receive admonition?" (Quran 54:17)

goodluck
