Sunan an-Nasa'i, Volume 2, Book 11, Hadith 978 (DarusSalam) ⓘ
It was narrated from Abdullah bin Abi Qatadah that his father said: "The Messenger of Allah used to recite the Umm Al-Quran and two surahs in the first two rak'ahs of Zuhr and 'Asr, and in the last two with Umm Al-Quran, and he would make us hear a verse sometimes, and he used to make the first rak'ah lengthy."
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، قَالَ حَدَّثَنَا أَبَانُ بْنُ يَزِيدَ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ بِأُمِّ الْقُرْآنِ وَسُورَتَيْنِ وَفِي الأُخْرَيَيْنِ بِأُمِّ الْقُرْآنِ وَكَانَ يُسْمِعُنَا الآيَةَ أَحْيَانًا وَكَانَ يُطِيلُ أَوَّلَ رَكْعَةٍ مِنْ صَلاَةِ الظُّهْرِ .
