(Imām Bukhārī narrates): Mūsā ibn Ismā'īl narrated to us, he said: Hammām narrated to us, from Yahyā, from 'Abdullāh ibn Abī Qatādah, from his father, that the Prophet ﷺ used to recite Sūrat al-Fātihah and two sūrahs in the first two rak'ahs of Zuhr, and used to recite Sūrat al-Fātihah in the last two rak'ahs and made us hear it, and he used to recite the first rak'ah longer than he recited the second rak'ah, and similarly in 'Asr, and similarly in Fajr.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا هَمَّامٌ، عَنْ يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَقْرَأُ فِي الظُّهْرِ فِي الأُولَيَيْنِ بِأُمِّ الْكِتَابِ وَسُورَتَيْنِ، وَفِي الرَّكْعَتَيْنِ الأُخْرَيَيْنِ بِأُمِّ الْكِتَابِ، وَيُسْمِعُنَا الآيَةَ، وَيُطَوِّلُ فِي الرَّكْعَةِ الأُولَى مَا لاَ يُطَوِّلُ فِي الرَّكْعَةِ الثَّانِيَةِ، وَهَكَذَا فِي الْعَصْرِ وَهَكَذَا فِي الصُّبْحِ.
