When you pray i heard that you must move your lips. I am confused whether or not this is sunnat or fard? Also if you do have to do this, do you have to move your lips to every syllable in salat? I am finding this very hard to do. It took me 25 minutes to pray Dhur and i am feeling very overwhelmed and stressed, instead of relaxed. Please let me know.
Say, "Call upon Allah or call upon the Most Merciful. Whichever [name] you call - to Him belong the best names." And do not recite [too] loudly in your prayer or [too] quietly but seek between that an [intermediate] way.
So, while adjusting the volume, you can automatically adjust the movement of your lips, can't you? And I don't think there any Hadith which talk about this matter. So, if someone finds something, please do add it.
Allah knows the best.
