Quran is come down from Allah you Jahiliya (as Prophet called your nation) idol worshippers.(sure we were idol worshiper and infidel like all humanity but we believed in gods not cows and suns like you or even human being) When we believed in God, we had Holy Book(there is no holy book except Quran), Prophet, religion, spirituality, you were bowing down to stone idols and worshipped camel's pudendum and whatever came out of it. You killed your relatives and children to sacrifice your hand maded idols.
Don't forget your atheist forefathers before getting Muslims fought 80 wars against Prophet Muhammad (s) but they got defeated because they lacked eman (faith) and intelligence.(all religion originated from our land cow worshiper)
Allah has bashed your idol worshiper forefathers and foremothers in many Ayas of noble(noble?) Quran.(yeah bashed all infidels and we became Muslims and god forgave us )
..And even if We had revealed Quran to the ' Ajams ' [26.198](so you changed quran thats nifaq and shirk)
And he [prophet] had recited it to them [perfectly], they would [still] not have been believers in it. [26.199]
Thus have We inserted disbelief into the hearts of sinners [Arabs]. [26.200]
