(a) Qatadah (may Allah have mercy on him) said that someone asked Sayyiduna Anas bin Malik (may Allah be pleased with him): How was the recitation of the Messenger of Allah (peace and blessings be upon him)? He said that he used to prolong (the sounds). Then he recited 'In the name of Allah, the Most Gracious, the Most Merciful' [Surah al-Fatihah: 1], prolonging 'al-Rahman' and also prolonging 'al-Rahim'.
(b) Imam al-Bukhari (may Allah have mercy on him) narrated it in his Sahih from Amr bin Asim, who narrates it from Hammam, except that in it he prolonged 'Bismillah', then prolonged 'al-Rahman' and also prolonged 'al-Rahim'.
