question #1 Sahih Muslim 398a, Book 4, Hadith 49 : What is the significance of reciting Quranic verses during prayer in Islam?

The Messenger of Allah (may peace beupon him) led us In Zuhr or ‘Asr prayer (noon or the afternoon prayer). (On concluding it) he said: Who recited behind me (the verses): Sabbih Isma Rabbik al-a’la (Glorify the name of thy Lord, the Most High)? There upon a person said: It was I, but I in- tended nothing but goodness. I felt that some one of you was disputing with me in it (or he was taking out from my tongue what I was reciting), said the Prophet (ﷺ).
