Sahih Muslim — The Book of Prayers — Hadith No: 884
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - عَنْ حَبِيبٍ الْمُعَلِّمِ، عَنْ عَطَاءٍ، قَالَ قَالَ أَبُو هُرَيْرَةَ فِي كُلِّ صَلاَةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا النَّبِيُّ صلى الله عليه وسلم أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَاهُ مِنْكُمْ وَمَنْ قَرَأَ بِأُمِّ الْكِتَابِ فَقَدْ أَجْزَأَتْ عَنْهُ وَمَنْ زَادَ فَهُوَ أَفْضَلُ .
Translation
Ata' reported it on the authority of Abu Huraira who said:Recitation (of Surat al-Fatiha) in every (rak'ah) of prayer in essential. (The recitation) that we listened to from the Messenger of Allah (ﷺ) we made you listen to it. And that which he recited inwardly to us, we recited it inwardly for you. And he who recites Umm al-Qur'an, it is enough for him (to complete the prayer), and he who adds to it (recites some other verses of the Holy Qur'an along with Surat al-Fatiha), it is preferable for him
