Preserving The 'dhikr'
Quran has been called Al-Kitaab, Al-Hikmah, Al-Furqan, Al-Huda and Adh-Dikhr. The sentence structure and context makes it clear that in what meaning these words are used and what exactly are they referring to. If you look at the flow of verses (15:6-9), it becomes evident that Dikhr here can only means this Quran. Linguistically, there are no two possibilities.
