It is narrated from Ata that Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: "Recitation is to be done in every prayer." What the Messenger of Allah (peace and blessings be upon him) let us hear, we have let you hear, and what was kept hidden from us, we have kept hidden from you as well. A man said: What is your view if I do not recite more than Surah al-Fatihah? He (may Allah be pleased with him) said: If you recite more than it, that is better, and if you suffice with it, that is also enough.
