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  

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.  

أَبُو هُرَيْرَةَ فِي كُلِّ صَلاَةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا النَّبِيُّ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَاهُ مِنْكُمْ وَمَنْ قَرَأَ بِأُمِّ الْكِتَابِ فَقَدْ أَجْزَأَتْ عَنْهُ وَمَنْ زَادَ فَهُوَ أَفْضَلُ  

"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  

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. (Using translation from Muslim 396b)   

قَالَ أَبُو هُرَيْرَةَ ؓ فِي كُلِّ صَلَاةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا رَسُولُ اللهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى أَخْفَيْنَاهُ مِنْكُمْ فَقَالَ رَجُلٌ أَرَأَيْتَ إِنْ لَمْ أَزِدْ عَلَى أُمِّ الْقُرْآنِ؟ قَالَ إِنْ زِدْتَ عَلَيْهَا فَهُوَ خَيْرٌ وَإِنِ انْتَهَيْتَ عَلَيْهَا أَجْزَأَتْ عَنْكَ
