Is it understood from the saying "you read it while asleep and awake" in the Hadith that it is permissible to read the Quran silently without moving the tongue?

Scholars have differed in interpreting the phrase "you recite it while asleep and awake." Some said its meaning is that it is preserved for you in both states, while others said it means you recite it with ease and facility, or that it becomes a skill for you such that it is present in your mind and you do not neglect it.

As for reciting the Qur'an by heart without moving the tongue, none of the scholars have ever said that. Rather, they have unanimously agreed that recitation must involve movement of the tongue, such that the reciter hears himself. Their evidence is that one who contemplates the Qur'an with his heart without moving his tongue is not considered a reciter, and therefore the ruling of recitation does not apply to him, such as breaking an oath or the prohibition of a ritually impure person reciting. The Hanafis, Malikis, and Shafi'is all emphasize the necessity of moving the tongue and lips in recitation and dhikr (remembrance), because these are utterances that are not achieved without it.
