Ubaydullah bin Abi Rafi' narrates from Sayyiduna Ali (may Allah be pleased with him) that he (may Allah be pleased with him) used to order or encourage that, behind the imam, in the first two rak'ahs of Zuhr and Asr, Surah al-Fatihah and one more surah be recited, and he used to order that in the last two rak'ahs only Surah al-Fatihah be recited.
