This gesticulating is an error because the Prophet (peace be on him) raised his palms only for supplication. Here you may glorify and magnify Allah the Most High, supplicating Him in any words you wish while facing the direction of the Kabah. It is preferable to recite the dhikr which the Prophet (peace be on him) recited at Safa and Marwah.
