(Imām Bukhārī narrates): Abdullah bin Yusuf narrated the hadith to us, he said: Imam Malik informed us, from Abdullah bin Yazid and Abi al-Nadr, the freed slave of Umar bin Ubaidullah, from Abi Salamah bin Abdur Rahman, from Hazrat Aishah Umm al-Mu'minin (Allāh be pleased with her), that
the Messenger of Allāh ﷺ used to offer prayer sitting, so he ﷺ would recite the Qur'an sitting, then when about thirty or forty verses remained of his ﷺ recitation, he ﷺ would stand up and recite those verses standing, then he ﷺ would perform ruku, then perform sujud, and he ﷺ would offer the second rak'ah in the same way, then when he ﷺ finished the prayer, he ﷺ would look, so if I was awake, he ﷺ would talk with me, and if I was asleep, he ﷺ would lie down.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، وَأَبِي النَّضْرِ مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ أُمِّ المُؤْمِنِينَ رَضِي اللَّهُ عَنْهَا
أَنَّ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ كَانَ يُصَلِّي جَالِسًا، فَيَقْرَأُ وَهُوَ جَالِسٌ، فَإِذَا بَقِيَ مِنْ قِراءَتِهِ نَحْوٌ مِنْ ثَلاَثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ فَقَرَأَهَا وَهُوَ قَائِمٌ، ثُمَّ يَرْكَعُ، ثُمَّ سَجَدَ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ، فَإِذَا قَضَى صَلاَتَهُ نَظَرَ فَإِنْ كُنْتُ يَقْظَى تَحَدَّثَ مَعِي، وَإِنْ كُنْتُ نَائِمَةً اضْطَجَعَ
