What is said in bowing and prostration, and what is best regarding the number of recitations

Question:
May Allah reward you with good and do you well. The sender of this letter, Jihan Abdul Hamid, says: I try during my prayer to recite all the dhikr (remembrance of Allah) I have heard for bowing and prostration, and I also perform some voluntary acts, which makes my prayer somewhat long. Is it obligatory for me to shorten my prayer if I have a friend or a relative who is bothered by the length of my prayer?

Answer:
What is required in bowing and prostration is to say "Subhan Rabbi al-Azim" (Glory be to my Lord, the Magnificent) in bowing, and "Subhan Rabbi al-A'la" (Glory be to my Lord, the Most High) in prostration, once. Anything added to that, whether three times, five times, seven times, or ten times, is all good; whatever is added is better. The minimum that suffices is once, the minimum of perfection is three, and the maximum is ten: ten glorifications in bowing and prostration. One should also make whatever supplication is easy for them, and the best approach is moderation. Praise be to Allah. The best for a Muslim is to take the middle path between excessive shortening and tedious lengthening. So, one should be moderate in their prayer, in their standing, in their bowing, and in their prostration; being moderate is the best and most excellent.
