"I asked "A'isha (may Allah be well pleased with her) about the Qur’anic recitation of the Prophet (Allah bless him and give him peace): “Was he used to whispering the recitation, or pronouncing it audibly?” She said: “He used
to do both. He would sometimes whisper and sometimes speak audibly.” I therefore said: “Praise be to Allah, who has granted us flexibility in the matter!”
"The Prophet (Allah bless him and give him peace) used to interrupt his Qur’anic recitation. He would say: “Praise be to Allah, the Lord of all the worlds .”
“I said to Anas ibn Malik: 'How was the Qur’anic recitation of Alla’s Messenger (Allah bless him and give him peace)?’ He said: ‘With the voice drawn out over the long vowels.'”
