Narrated Abu Qatadah: The Prophet ﷺ went out at night and found Abu Bakr praying in a low voice, and he passed Umar ibn al-Khattab who was raising his voice while praying. When they both met the Prophet ﷺ together, the Prophet ﷺ said: I passed by you, Abu Bakr, when you were praying in a low voice. He replied: I made Him hear with Whom I was holding intimate converse, Messenger of Allah. He (the Prophet) said to Umar: I passed by you when you were praying in a loud voice. He replied: Messenger of Allah, I was awakening the drowsy and driving away the Devil. Al-Hasan added in his version: The Prophet ﷺ said: Raise your voice a little, Abu Bakr, and he said to Umar: Lower your voice a little.
