Is it permissible for a Muslim to seek refuge in Allah and spit to their left three times during prayer if they feel the whispers of Satan, or should they do that after or before the prayer?

If a worshiper feels the whisperings of Satan during prayer, he should seek refuge in Allah from him and spit to his left three times. This involves expelling some air with a little saliva, and it should be done as soon as the whisperings are felt, even if it is during the prayer.
