حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا جَرِيرٌ، عَنْ قَتَادَةَ، قَالَ سَأَلْتُ أَنَسًا عَنْ قِرَاءَةِ النَّبِيِّ، صلى الله عليه وسلم فَقَالَ كَانَ يَمُدُّ مَدًّا .
Qatadah said: I asked Anas about the recitation of the Qur'an by the Prophet (ﷺ). He said: He used to express all the long accents clearly.
