The Qur'an is recited in every prayer and in those prayers in which Messenger of Allah ﷺ recited aloud for us, we recite aloud in the same prayers for you; and the prayers in which the Prophet ﷺ recited quietly, we recite quietly. If you recite "Al-Fatiha" only it is sufficient but if you recite something else in addition, it is better.  

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ ؓ يَقُولُ فِي كُلِّ صَلاَةٍ يُقْرَأُ فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى عَنَّا أَخْفَيْنَا عَنْكُمْ وَإِنْ لَمْ تَزِدْ عَلَى أُمِّ الْقُرْآنِ أَجْزَأَتْ وَإِنْ زِدْتَ فَهُوَ خَيْرٌ  

If I add nothing to the (recitation) of the Umm al Qur'an (Surat al-Fatiha), would it make the prayer incomplete? He (AbuHuraira) said: If you add to that (if you recite some of verses of the Qur'an along with Surat at-Fatiha) that is better for you. But if you are contented with it (Surat al-Fatiha) only, it is sufficient for you.  

أَبُو هُرَيْرَةَ فِي كُلِّ الصَّلاَةِ يَقْرَأُ فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَا مِنْكُمْ فَقَالَ لَهُ رَجُلٌ إِنْ لَمْ أَزِدْ عَلَى أُمِّ الْقُرْآنِ فَقَالَ إِنْ زِدْتَ عَلَيْهَا فَهُوَ خَيْرٌ وَإِنِ انْتَهَيْتَ إِلَيْهَا أَجْزَأَتْ عَنْكَ  

"Abu Hurairah said: "In should be recitation in every prayer. 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.'"  

أَبُو هُرَيْرَةَ كُلُّ صَلاَةٍ يُقْرَأُ فِيهَا فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَاهَا أَخْفَيْنَا مِنْكُمْ  

In every prayer there is a recitation. We make you listen what the Messenger of Allah ﷺ made us listen, and we keep hidden from you what he kept hidden from us. (Using translation from Abū Dāʾūd 797)   

أَبُو هُرَيْرَةَ كُلُّ صَلَاةٍ يُقْرَأُ فِيهَا فَمَا أَسْمَعَنَا رَسُولُ اللهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى عَلَيْنَا أَخْفَيْنَا عَلَيْكُمْ  

"Abu Hurairah said: "In should be recitation in every prayer. 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.'" (Using translation from Nasāʾī 969)   

«كُلُّ الصَّلَاةِ يُقْرَأُ فِيهَا فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَا مِنْكُمْ»  

[Machine] I heard Abu Hurairah saying, "In every prayer, there is recitation." So we never heard the Messenger of Allah (PBUH) reciting so loudly that you could hear him, nor did he recite so softly that you could not hear him.  

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ «فِي كُلِّ صَلَاةٍ قِرَاءَةٌ» فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى عَلَيْنَا أَخْفَيْنَا عَنْكُمْ  

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. (Using translation from Muslim 396c)   

قَالَ أَبُو هُرَيْرَةَ ؓ فِي كُلِّ صَلَاةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا النَّبِيُّ ﷺ أَسْمَعْنَاكُمْ وَمَا أُخْفَى مِنَّا أَخْفَيْنَاهُ مِنْكُمْ فَقَدْ أَجْزَأَتْ عَنْهُ وَمَنْ زَادَ فَهُوَ أَفْضَلُ
