And the infidels said, 'We shall never believe, in this Quran and nor in those books which were before it.' And if you could see when the unjust will be made to stand before their Lord; they shall cast back the word one against the other, those who were pressed will say to those who were swelled with pride, 'if you had not been, we would surely have believed.' [34:31]
The Prophet (Sal-allahu-aleihi-wasallam) said, "Reciting the Qur'an during prayer is more excellent than reciting it at other times, and reciting the Qur'an at a time other than during prayer is more excellent than extolling Allah and declaring His greatness. Extolling Allah is more excellent than sadaqah, sadaqah is more excellent than fasting, and fasting is a protection from Hell."
