It is narrated about Sayyiduna Ali (may Allah be pleased with him): He used to command this (the narrator is in doubt, perhaps these are the words) he used to like this: "In the first two rak'ahs of Zuhr and Asr, Surah Al-Fatihah and along with it any one Surah should be recited, and in the last two rak'ahs only Surah Al-Fatihah should be recited, at the time when a person is performing prayer behind the Imam." The chain of this narration is authentic.
