The specific prayer you're referring to depends on which prayer you're asking about. Could you please clarify which prayer you have in mind? For example, are you asking about:
* The Lord's Prayer (Our Father): Recorded in the Gospels of Matthew (Matthew 6:9-13) and Luke (Luke 11:2-4) in the Bible.
* The Shema Yisrael prayer: Found in the Book of Deuteronomy (Deuteronomy 6:4) in the Hebrew Bible (Tanakh/Old Testament).
* The Salutation to the Prophet (Salawat): Found in the Quran in Surah Al-Ahzab (33:56).
* A specific prayer from a particular religion or tradition?
Once I know which prayer you're interested in, I can give you a more accurate answer.
