It was narrated that Abu Hurairah said:

"In every prayer there is recitation. What the Messenger of Allah (ﷺ) made us hear (by reciting out loud) we make you hear, and what he hid from us (by reciting silently) we hide from you."

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ أَنْبَأَنَا خَالِدٌ، قَالَ حَدَّثَنَا ابْنُ جُرَيْجٍ، عَنْ عَطَاءٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ فِي كُلِّ صَلاَةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَسْمَعْنَاكُمْ وَمَا أَخْفَاهَا أَخْفَيْنَا مِنْكُمْ ‏.‏
