Sayyiduna Abu Qatadah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) used to recite Surah Al-Fatihah and an additional Surah in each of the first two rak‘ahs of the Zuhr prayer, and sometimes he would let us hear a verse. He used to make the first rak‘ah longer than the second, and in each of the last two rak‘ahs, he would recite (only) Surah Al-Fatihah. Abu Qatadah says: In the ‘Asr and Fajr prayers, he used to do the same. Abu Muhammad (may Allah have mercy on him) says: This narration is also reported through another chain, but in that, there is no mention of the Fajr prayer.
