Sahih Muslim, Chapter: Prayers (Kitab Al-Salat)

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 Holy Prophet (may peace be upon him).
