He used to sleep in the early part of the night, and woke up in the latter part. If he then wished intercourse with his wife, he satisfied his desire, and then went to sleep; and when the first call to prayer was made he jumped up (by Allah, she, i. e. 'A'isha, did not say" he stood up" ), and poured water over him (by Allah she, i. e. 'A'isha, did not say that he took a bath but I know what she meant) and if he did not have an intercourse, he performed ablution, just as a man performs ablution for prayer and then observed two rak'ahs.  

عَنْ صَلاَةِ رَسُولِ اللَّهِ ﷺ قَالَتْ كَانَ يَنَامُ أَوَّلَ اللَّيْلِ وَيُحْيِي آخِرَهُ ثُمَّ إِنْ كَانَتْ لَهُ حَاجَةٌ إِلَى أَهْلِهِ قَضَى حَاجَتَهُ ثُمَّ يَنَامُ فَإِذَا كَانَ عِنْدَ النِّدَاءِ الأَوَّلِ قَالَتْ وَثَبَ وَلاَ وَاللَّهِ مَا قَالَتْ قَامَ فَأَفَاضَ عَلَيْهِ الْمَاءَ وَلاَ وَاللَّهِ مَا قَالَتِ اغْتَسَلَ وَأَنَا أَعْلَمُ مَا تُرِيدُ وَإِنْ لَمْ يَكُنْ جُنُبًا تَوَضَّأَ وُضُوءَ الرَّجُلِ لِلصَّلاَةِ ثُمَّ صَلَّى الرَّكْعَتَيْنِ  

[Machine] About the salah (prayer) of the Messenger of Allah ﷺ , he said: I asked, "Was the Messenger of Allah ﷺ accustomed to sleeping at the beginning of the night and waking up at the end of it?" He replied, "Yes." When he woke up, he would perform ablution and pray the portion of salah that Allah had obligated upon him. If he had a need to attend to his family, he would go to them, and if not, he would go back to his bed. If he went to his family, he would sleep in whatever state he was in, without touching water, until when the first athan (call to prayer) was given, he would wake up. By Allah, he would not say, "He woke up", but rather, "He stood up." And if he was in a state of sexual impurity (junub), he would pour water over himself. By Allah, he would not say, "He washed himself", but rather, "He poured water over himself." Otherwise, he would perform ablution and then pray two units of prayer (rakatayn), and then he would go out to the masjid.  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ؟ قَالَ فَقُلْتُ كَانَ رَسُولُ اللهِ ﷺ يَنَامُ أَوَّلَهُ وَيَقُومُ آخِرَهُ فَإِذَا قَامَ تَوَضَّأَ وَصَلَّى مَا قَضَى الله ﷻ لَهُ فَإِنْ كَانَ بِهِ حَاجَةٌ إِلَى أَهْلِهِ أَتَى أَهْلَهُ وَإِلَّا مَالَ إِلَى فِرَاشِهِ فَإِنْ كَانَ أَتَى أَهْلَهُ نَامَ كَهَيْئَتِهِ لَمْ يَمَسَّ مَاءً حَتَّى إِذَا كَانَ عِنْدَ أَوَّلِ الْأَذَانِ وَثَبَ وَاللهِ مَا قَالَتْ قَامَ وَإِنْ كَانَ جُنُبًا أَفَاضَ عَلَيْهِ الْمَاءَ وَاللهِ مَا قَالَتْ اغْتَسَلَ وَإِلَّا تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ صَلَّى رَكْعَتَيْنِ ثُمَّ خَرَجَ إِلَى الْمَسْجِدِ  

He used to sleep in the early part of the night, and woke up in the latter part. If he then wished intercourse with his wife, he satisfied his desire, and then went to sleep; and when the first call to prayer was made he jumped up (by Allah, she, i. e. 'A'isha, did not say" he stood up" ), and poured water over him (by Allah she, i. e. 'A'isha, did not say that he took a bath but I know what she meant) and if he did not have an intercourse, he performed ablution, just as a man performs ablution for prayer and then observed two rak'ahs. (Using translation from Muslim 739)  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ قَالَتْ كَانَ يَنَامُ أَوَّلَ اللَّيْلِ وَيُحْيِي آخِرَهُ ثُمَّ إِنْ كَانَتْ لَهُ حَاجَةٌ إِلَى أَهْلِهِ قَضَى حَاجَتَهُ ثُمَّ نَامَ قَبْلَ أَنْ يَمَسَّ مَاءً فَإِذَا كَانَ عِنْدَ النِّدَاءِ الْأَوَّلِ قَالَتْ وَثَبَ وَلَا وَاللهِ مَا قَالَتْ قَامَ فَأَفَاضَ عَلَيْهِ الْمَاءَ وَلَا وَاللهِ مَا قَالَتْ اغْتَسَلَ وَأَنَا أَعْلَمُ بِمَاتُرِيدُ وَإِنْ لَمْ يَكُنْ جُنُبًا تَوَضَّأَ وُضُوءَ الرَّجُلِ لِلصَّلَاةِ ثُمَّ صَلَّى الرَّكْعَتَيْنِ  

[Machine] Regarding the prayer of the Messenger of Allah ﷺ , she said: He used to sleep at the beginning of the night and wake up at the end of it, and sometimes he needed to be with his family. Then he would sleep before touching water. When the first call to prayer was made, he would quickly respond, and she said: He would stand up and the water would be poured over him, and she said: He did not say that he washed, and I know what he intended. And if he was not in a state of janabah (major ritual impurity), he would perform wudu (ablution) for the prayer, just like a man does for prayer.  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ فَقَالَ قَالَتْ كَانَ يَنَامُ أَوَّلَ اللَّيْلِ وَيُحْيِي آخِرَهُ فَرُبَّمَا كَانَتْ لَهُ الْحَاجَةُ إِلَى أَهْلِهِ ثُمَّ يَنَامُ قَبْلَ أَنْ يَمَسَّ مَاءً فَإِذَا كَانَ عِنْدَ النِّدَاءِ الْأَوَّلِ وَثَبَ وَمَا قَالَتْ قَامَ فَأَفَاضَ عَلَيْهِ الْمَاءَ وَمَا قَالَتْ اغْتَسَلَ وَأَنَا أَعْلَمُ مَا تُرِيدُ وَإِنْ لَمْ يَكُنْ جُنُبًا تَوَضَّأَ وُضُوءَ الرَّجُلِ لِلصَّلَاةِ
