وَعَنْ أَبِي قَتَادَةَ قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ لَيْلَةً فَإِذَا هُوَ بِأَبِي بَكْرٍ يُصَلِّي يَخْفِضُ مِنْ صَوْتِهِ وَمَرَّ بِعُمَرَ وَهُوَ يُصَلِّي رَافِعًا صَوْتَهُ قَالَ: فَلَمَّا اجْتَمَعَا عِنْدَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «يَا أَبَا بَكْرٍ مَرَرْتُ بِكَ وَأَنْتَ تُصَلِّي تَخْفِضُ صَوْتَكَ» قَالَ: قَدْ أَسْمَعْتُ مَنْ نَاجَيْتُ يَا رَسُولَ اللَّهِ وَقَالَ لِعُمَرَ: «مَرَرْتُ بِكَ وَأَنْتَ تُصَلِّي رَافِعًا صَوْتَكَ» فَقَالَ: يَا رَسُولَ اللَّهِ أُوقِظُ الْوَسْنَانَ وَأَطْرُدُ الشَّيْطَانَ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَا أَبَا بَكْرٍ ارْفَعْ مِنْ صَوْتِكَ شَيْئًا» وَقَالَ لِعُمَرَ: «اخْفِضْ مِنْ صَوْتِكَ شَيْئًا» . رَوَاهُ أَبُو دَاوُد وروى التِّرْمِذِيّ نَحوه
Abu Qatada said God’s Messenger went out one night and found Abu Bakr praying in a low voice, and he passed ‘Umar who was raising his voice while praying. When they both were with the Prophet he said, “I passed 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 God.” He said to ‘Umar, “I passed you when you were raising your voice while praying.” He replied, “Messenger of God, I was wakening the drowsy and driving away the devil.” The Prophet said, “Raise your voice a little, Abu Bakr;” and he said to ‘Umar, “Lower your voice a little.” Abu Dawud transmitted it, and Tirmidhi transmitted something similar.
