And when Our clear signs are recited unto them, then those who hope not to meet Us begin to say, 'bring a Quran other than this, or alter it. Say you, 'it is not for me to change it on my own accord. I only follow, what is revealed to me if I disobey my Lord, then I fear the torment of the great Day.[10:15]
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."
