Establish prayer from declining of the sun till the darkening of the night and the Quran of the dawn. No doubt, angles are present in the Quran of the dawn.[17:78]
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."
