Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ اعْتَكَفَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْمَسْجِدِ فَسَمِعَهُمْ يَجْهَرُوا بِالْقِرَاءَةِ وَهُوَ فِي قُبَّةٍ لَهُ فَكَشَفَ السُّتُورَ وَكَشَفَ وَقَالَ أَلَا كُلُّكُمْ مُنَاجٍ رَبَّهُ فَلَا يُؤْذِيَنَّ بَعْضُكُمْ بَعْضًا وَلَا يَرْفَعَنَّ بَعْضُكُمْ عَلَى بَعْضٍ فِي الْقِرَاءَةِ أَوْ قَالَ فِي الصَّلَاةِ.
English Translation
Abd al-Razzaq told us, Ma'mar told us, from Isma'il ibn Umayyah, from Abu Salamah ibn Abd al-Rahman, from Abu Sa'id al-Khudri, who said: The Messenger of Allah (peace and blessings be upon him) was in spiritual retreat in the mosque, and he heard them raising their voices in recitation while he was in a small tent of his. He drew back the curtains and uncovered [himself] and said: "Indeed, each of you is confiding in his Lord, so let none of you harm another, and let none of you raise his voice over another in recitation" - or he said: "in prayer."
