حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا قَتَادَةُ، عَنْ زُرَارَةَ بْنِ أَوْفَى، عَنْ سَعْدِ بْنِ هِشَامٍ، قَالَ ‏: ‏ طَلَّقْتُ امْرَأَتِي فَأَتَيْتُ الْمَدِينَةَ لأَبِيعَ عَقَارًا كَانَ لِي بِهَا، فَأَشْتَرِيَ بِهِ السِّلاَحَ وَأَغْزُوَ، فَلَقِيتُ نَفَرًا مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَقَالُوا ‏: ‏ قَدْ أَرَادَ نَفَرٌ مِنَّا سِتَّةٌ أَنْ يَفْعَلُوا ذَلِكَ فَنَهَاهُمُ النَّبِيُّ صلى الله عليه وسلم وَقَالَ ‏: ‏ ‏"‏ لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ ‏"‏ ‏.‏ فَأَتَيْتُ ابْنَ عَبَّاسٍ فَسَأَلْتُهُ عَنْ وِتْرِ النَّبِيِّ صلى الله عليه وسلم فَقَالَ ‏: ‏ أَدُلُّكَ عَلَى أَعْلَمِ النَّاسِ بِوِتْرِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَأْتِ عَائِشَةَ رضى الله عنها ‏.‏ فَأَتَيْتُهَا فَاسْتَتْبَعْتُ حَكِيمَ بْنَ أَفْلَحَ فَأَبَى فَنَاشَدْتُهُ فَانْطَلَقَ مَعِي، فَاسْتَأْذَنَّا عَلَى عَائِشَةَ، فَقَالَتْ ‏: ‏ مَنْ هَذَا قَالَ ‏: ‏ حَكِيمُ بْنُ أَفْلَحَ ‏.‏ قَالَتْ ‏: ‏ وَمَنْ مَعَكَ قَالَ ‏: ‏ سَعْدُ بْنُ هِشَامٍ ‏.‏ قَالَتْ ‏: ‏ هِشَامُ بْنُ عَامِرٍ الَّذِي قُتِلَ يَوْمَ أُحُدٍ قَالَ قُلْتُ ‏: ‏ نَعَمْ ‏.‏ قَالَتْ ‏: ‏ نِعْمَ الْمَرْءُ كَانَ عَامِرًا ‏.‏ قَالَ قُلْتُ ‏: ‏ يَا أُمَّ الْمُؤْمِنِينَ حَدِّثِينِي عَنْ خُلُقِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَتْ ‏: ‏ أَلَسْتَ تَقْرَأُ الْقُرْآنَ فَإِنَّ خُلُقَ رَسُولِ اللَّهِ صلى الله عليه وسلم كَانَ الْقُرْآنَ ‏.‏ قَالَ قُلْتُ ‏: ‏ حَدِّثِينِي عَنْ قِيَامِ اللَّيْلِ قَالَتْ ‏: ‏ أَلَسْتَ تَقْرَأُ ‏{‏ يَا أَيُّهَا الْمُزَّمِّلُ ‏}‏ قَالَ قُلْتُ ‏: ‏ بَلَى ‏.‏ قَالَتْ ‏: ‏ فَإِنَّ أَوَّلَ هَذِهِ السُّورَةِ نَزَلَتْ، فَقَامَ أَصْحَابُ رَسُولِ اللَّهِ صلى الله عليه وسلم حَتَّى انْتَفَخَتْ أَقْدَامُهُمْ، وَحُبِسَ خَاتِمَتُهَا فِي السَّمَاءِ اثْنَىْ عَشَرَ شَهْرًا، ثُمَّ نَزَلَ آخِرُهَا فَصَارَ قِيَامُ اللَّيْلِ تَطَوُّعًا بَعْدَ فَرِيضَةٍ ‏.‏ قَالَ قُلْتُ ‏: ‏ حَدِّثِينِي عَنْ وِتْرِ النَّبِيِّ صلى الله عليه وسلم ‏.‏ قَالَتْ ‏: ‏ كَانَ يُوتِرُ بِثَمَانِ رَكَعَاتٍ لاَ يَجْلِسُ إِلاَّ فِي الثَّامِنَةِ، ثُمَّ يَقُومُ فَيُصَلِّي رَكْعَةً أُخْرَى، لاَ يَجْلِسُ إِلاَّ فِي الثَّامِنَةِ وَالتَّاسِعَةِ، وَلاَ يُسَلِّمُ إِلاَّ فِي التَّاسِعَةِ، ثُمَّ يُصَلِّي رَكْعَتَيْنِ وَهُوَ جَالِسٌ فَتِلْكَ إِحْدَى عَشْرَةَ رَكْعَةً يَا بُنَىَّ، فَلَمَّا أَسَنَّ وَأَخَذَ اللَّحْمَ أَوْتَرَ بِسَبْعِ رَكَعَاتٍ لَمْ يَجْلِسْ إِلاَّ فِي السَّادِسَةِ وَالسَّابِعَةِ، وَلَمْ يُسَلِّمْ إِلاَّ فِي السَّابِعَةِ، ثُمَّ يُصَلِّي رَكْعَتَيْنِ وَهُوَ جَالِسٌ، فَتِلْكَ هِيَ تِسْعُ رَكَعَاتٍ يَا بُنَىَّ، وَلَمْ يَقُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيْلَةً يُتِمُّهَا إِلَى الصَّبَاحِ، وَلَمْ يَقْرَإِ الْقُرْآنَ فِي لَيْلَةٍ قَطُّ، وَلَمْ يَصُمْ شَهْرًا يُتِمُّهُ غَيْرَ رَمَضَانَ، وَكَانَ إِذَا صَلَّى صَلاَةً دَاوَمَ عَلَيْهَا، وَكَانَ إِذَا غَلَبَتْهُ عَيْنَاهُ مِنَ اللَّيْلِ بِنَوْمٍ صَلَّى مِنَ النَّهَارِ ثِنْتَىْ عَشْرَةَ رَكْعَةً ‏.‏ قَالَ ‏: ‏ فَأَتَيْتُ ابْنَ عَبَّاسٍ فَحَدَّثْتُهُ ‏.‏ فَقَالَ ‏: ‏ هَذَا وَاللَّهِ هُوَ الْحَدِيثُ، وَلَوْ كُنْتُ أُكَلِّمُهَا لأَتَيْتُهَا حَتَّى أُشَافِهَهَا بِهِ مُشَافَهَةً ‏.‏ قَالَ قُلْتُ ‏: ‏ لَوْ عَلِمْتُ أَنَّكَ لاَ تُكَلِّمُهَا مَا حَدَّثْتُكَ ‏.‏

Narrated Sa'd bin Hisham: I divorced my wife. I then came to Medina to sell my land that was there so that I could buy arms and fight in battle. I met a group of the Companions of the Prophet (ﷺ). They said: Six persons of us intended to do so (i.e. divorce their wives and purchase weapons), but the Prophet (ﷺ) prohibited them. He said: For you in the Messenger of Allah there is an excellent model. I then came to Ibn 'Abbas and asked him about the witr observed by the Prophet (ﷺ). He said: I point to you a person who is most familiar with the witr observed by the Messenger of Allah (ﷺ). Go to 'Aishah. While going to her I asked Hakim b. Aflah to accompany me. He refused, but I adjured him. He, therefore, went along with me. We sought permission to enter upon 'Aishah. She said: Who is this ? He said: Hakim b. Aflah. She asked: Who is with you ? He replied: Sa'd b. Hisham. She said: Hisham son of 'Amir who was killed in the Battle of Uhud. I said: Yes. She said: What a good man 'Amir was! I said: Mother of faithful, tell me about the character of the Messenger of Allah (ﷺ). She asked: Do you not recite the Quran? The character of Messenger of Allah (ﷺ) was the Qur'an. I asked: Tell me about his vigil and prayer at night. She replied: Do you not recite: "O thou folded in garments" (73: 1). I said: Why not? When the opening of this Surah was revealed, the Companions stood praying (most of the night) until their feet swelled, and the concluding verses were not revealed for twelve months from heaven. At last, the concluding verses were revealed, and the prayer at night became voluntary after it was obligatory. I said: Tell me about the witr of the Prophet (ﷺ). She replied: He used to pray eight rak'ahs, sitting only during the eighth of them. Then he would stand up and pray another rak'ahs. He would sit only after the eighth and the ninth rak'ahs. He would utter salutation only after the ninth rak'ah. He would then pray two rak'ahs sitting and that made eleven rak'ahs, O my son. But when he grew old and became fleshy he observed a witr of seven, sitting only in sixth and seventh rak'ahs, and would utter salutation only after the seventh rak'ah. He would then pray two rak'ahs sitting, and that made nine rak'ahs, O my son. The Messenger of Allah (ﷺ) would not pray through a whole night, or recite the whole Qur'an in a night or fast a complete month except in Ramadan. When he offered prayer, he would do that regularly. When he was overtaken by sleep at night, he would pray twelve rak'ahs. The narrator said: I came to Ibn 'Abbas and narrated all this to him. By Allah, this is really a tradition. Has I been on speaking terms with her, I would have come to her and heard it from her mouth. I said: If I knew that you were not on speaking terms with her, I would have never narrated it to you.
