Perhaps Allah will not subject them to annihilation here below on account of the Book -the Quran- which gives free circulation of divine enlightenment and information. The same course of action was adopted when We gave Mussa the Book - AL-Tawrah (the Torah)- and his people were disputant about it, and had it not been for Allah's word proclaimed beforehand to put punishment in respite, their Hereafter would have been planted in the now. Those people were as suspicious of AL- Tawrah, as your people -O Muhammad- are of the Quran.
