What is the interpretation of Allah Almighty's saying: "And remember your Lord within yourself, humbly and in awe, and without loudness in words...", and does the verse permit remembrance without moving the tongue?

The interpretation of verse 205 from Surah Al-A'raf, "And remember your Lord within yourself, humbly and with fear, and without loudness in words, in the mornings and in the evenings. And do not be among the heedless," is that it is a command to remember Allah secretly, with humility and fear, and not aloud, especially in the early morning and late afternoon, coupled with a warning against heedlessness. Scholars have differed regarding the remembrance of the heart without the tongue; some believe it is not a valid form of remembrance, while others consider it valid, with the remembrance by both heart and tongue being the most complete form.
