Shama-il Tirmidhi Chapter 43, Hadith Number 1 (297).

Ya’laa bin Mamlak Radiyallahu ‘Anhu says: “He asked Ummul Mu’mineen Sayyiditina Ummi Salamah Radiyallahu ‘Anha about the recital of Rasulullah Sallallahu ‘Alayhi Wasallam”. She replied: “He recited every word separately and clearly”.

Commentary
When Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam recited he uttered every word distinctly and clearly. Sayyiditina Ummi Salamah Radiyallahu ‘Anha may have described this verbally, it may also be possible that she demonstrated the manner in which Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam recited, where from this explanation is apparent. The commentators on hadith give two explanations. The second explanation seems more appropriate. A hadith of this nature is mentioned by Sayyiditina Ummi Salamah Radiyallahu ‘Anha in hadith number three of this chapter, wherein she demonstrates how Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam recited.
