Is it permissible to supplicate during prostration without moving the tongue in order to save time and increase devotion?

Perhaps the congruence between the verse number and the serial number of the Danish products occurred by chance and not as a miraculous sign. Everything in the universe is by Allah's decree and will. Supplication without moving the tongue is not considered valid, as it is not deemed recitation. Imam An-Nawawi mentioned that a person in a state of ritual impurity (junub) or a menstruating woman (ha'id) is permitted to look at the Mus'haf and recite by heart without moving the tongue. What you are doing results in omitting supplication during prostration, and there is no sin in that because it is a recommended act (mustahabb), but it is advisable to be diligent in it because it is a moment when supplications are answered.
