'Ata' narrated on the authority of Abu Huraira who said that one should recite (al-Fatiha) in every (rak'ah of) prayer. What we heard (i. e. recitation) from the Messenger of Allah (ﷺ) , we made you listen to that. And that which he (recited) inwardly , we (recited) inwardly for you. A person said to him
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.
