Q:

Does it count in the eyes of Allah if we recite the Qur’an or dhikr or anything else worldy or religious without opening our mouths and just using our tongue? If not then please tell me what is the ruling on this?

A:

You are allowed to recite the heart in your mind, although involving our tongues and moving our lips would be better than doing it mentally.

When we involve each of our limbs (tongue, lips, mouth, heart, and mind) in recitation, we stand to gain multiple rewards as each of these limbs are involved in the noblest of deeds.

Having said this, it is fine to alternate: recite aloud in such a way you can hear it yourself sometimes, while doing so silently in your mind, at other times.

Allah Almighty knows best.
