Answer:
Stillness in the prayer is necessary (according to the more cautious opinion) when standing from the bowing position when sitting between the two prostrations. [Tahtawi, Shurunbulali; Hashiyat Maraqi al-Falah]
Pausing Between Recitations
If taking slight pauses in the prayer assists you in performing the prayer correctly, it is allowed as long as the pause is not the length of one integral (i.e., the extent of saying SubhanAllah three times.) [Ibn ‘Abidin, Radd al-Muhtar]
