Shama-il Tirmidhi Chapter 043, Hadith Number 003 (299).

Ummi Salamah Radiyallahu 'Anha reports: "Rasulullah Sallallahu 'Alayhi Wasallam recited every aayah separately. He recited 'Alhamdulillaahi Rabbil 'Aa-lameen' and paused, then recited 'Ar Rahmaanir Raheem' and paused. Then paused after reciting 'Maaliki Yawmiddeen'".

Commentary
Briefly, he recited every aayah distinctly, and with ease. There is a difference of opinion among the Qurraa, that is it afdal (better) to take a breath after the recital of every aayah or not? Maulana Gangohi has written a special booklet 'Raddut Tughyaan fi Awqaafil Qur-aan' in Urdu, which is quite comprehensive. This book is beneficial for the rnasaa-il of this nature.
