Imam Qatadah (may Allah have mercy on him) says: I asked Sayyiduna Anas bin Malik (may Allah be pleased with him), "How was the recitation of the Prophet (peace and blessings of Allah be upon him)?" He replied: The recitation of the Prophet (peace and blessings of Allah be upon him) used to be with elongation of the letters and words.
