Purity: Is Physical Stillness Required During Mustaḥabb Dhikr in Prayer?

English:

Question #342:

Should the body stand still completely while reciting the mustaḥabb dhikrs of prayers?

Answer #342:

There is no difference between obligatory and mustaḥabb dhikrs as far as the observing of the obligatory stillness and calmness during prayers is concerned. However, for dhikr which is not said as a part of the prayer, it is possible to say it in moving state.
