Does frequent recitation of the Qur’an create strength in the body and ward off laziness and drowsiness? And is it permissible to pray for blessing in the few hours of sleep, such as saying: "O Allah, make these few hours blessed so that I may be able to wake up for Fajr prayer"?

Reciting the Qur’an and performing night prayers (Qiyam al-Layl) are a cause for physical strength, because the Qur’an is a blessing and goodness. It is the best form of remembrance (dhikr), and the remembrance of Allah has an amazing effect on physical strength. It is prescribed for you to supplicate for blessings at the time of your sleep and throughout all your time.
