Does reciting the Qur’an at dawn without prayer achieve the reward of the non-heedless, the devout, or the Qintar (one who prays all night)? And how did our Master David pray, and did he sleep a sixth of the last third of the night?

"Whoever recites ten verses will not be recorded among the heedless; whoever recites a hundred verses will be recorded among the devout; and whoever recites a thousand verses will be recorded among the muqanṭirīn (those who amassed great rewards)."

David, peace be upon him, used to sleep half the night, stand in prayer for a third of it, and sleep for a sixth. This was because he adopted leniency with souls, fearing the weariness that could lead to abandoning worship. Also, sleeping after standing in prayer rests the body, removes the harm of staying up late, and allows one to approach the dawn prayer and the day's adhkar with energy. Moreover, it is closer to avoiding ostentation.
