Supplication in the bowing

Question:
He also has a question: Sometimes I supplicate while bowing, asking for forgiveness, repentance, and turning back to Allah. Some of the people praying told me that this action is not valid, so please guide us, may Allah bless you.

Answer:
It is not valid, but it is permissible; however, it is better to occupy the bowing with the glorification, "Subhan Rabbi al-Azim" (Glory be to my Lord, the Exalted), "Subhan Rabbi al-Azim." If you make supplication during it, there is no harm, but it is better to devote the bowing to the glorification. You should make the prostration and place the supplication in the prostration. The Messenger of Allah (peace and blessings be upon him) said, "As for the prostration, increase your supplication in it, for it is likely that it will be answered for you." In another hadith, he said, "The closest a servant is to his Lord is when he is in prostration." Yes.
