Is it permissible to say "Subhan Allah, Al-Hamdulillah, La Ilaha Illa Allah, Allahu Akbar, La Hawla Wa La Quwwata Illa Billah, Subhan Allah Wa Bihamdihi, Astaghfirullah Wa Atubu Ilaih, and Subhan Allah Wa Bihamdihi Adada Khalqihi Wa Rida Nafsihi Wa Zinata Arshihi Wa Midada Kalimatihi" and other multiplied adhkar in rukoo' (bowing) and sujood (prostration)? Is it recommendable to do so? And is its reward the same as its reward outside of prayer?

There is no impediment to reciting the aforementioned dhikr in bowing (rukūʿ) and prostration (sujūd), as it includes glorification (tasbīḥ), magnification (taʿẓīm), and supplication (duʿāʾ). However, it should be noted that it is preferable to increase supplication in prostration and magnification in bowing, based on the Prophet's (peace be upon him) saying: "As for bowing, glorify the Lord, the Mighty and Majestic, therein. And as for prostration, strive in supplication, for it is more likely that your prayers will be answered." It is also preferable to adhere to the remembrances (adhkār) authentically reported from the Prophet (peace be upon him).
