Is it permissible for a Muslim to go back to sleep after reciting the Qur’an and engaging in remembrance of Allah following Fajr prayer, knowing that he does not miss any prayer or obligation because of that?

"Behold, noonsleeps bequeath to the youth folly, and afternoon-sleeps, madness." This statement is not supported by any legal religious proof, even if some scholars affirmed it. Night sleep is better than day sleep, and Allah has blessed this nation in its early mornings. Many scholars deemed midday sleep good, and the Qur'an points to it: "{And when you lay aside your garments in the noonday}." It is disliked to sleep before the 'Isha prayer, and anything other than that is permissible.
