Abdullah bin Abu Qatadah narrates from his father that the Prophet Muhammad (peace be upon him) used to recite Surah Al-Fatihah and another Surah in the first two rak'ahs of Zuhr and Asr prayers. Sometimes he would let us hear a verse (i.e., he would recite aloud), and in the last two rak'ahs, he would recite only Surah Al-Fatihah.
