Messenger of Allah ﷺ used to pray eleven rakʿat at night and that was his night prayer and each of his prostrations lasted for a period enough for one of you to recite fifty verses before Messenger of Allah ﷺ raised his head. He also used to pray two rakʿat (Sunnah) before the (compulsory) Fajr prayer and then lie down on his right side till the Mu'adh-dhin came to him for the prayer.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي إِحْدَى عَشْرَةَ رَكْعَةً كَانَتْ تِلْكَ صَلاَتَهُ تَعْنِي بِاللَّيْلِ فَيَسْجُدُ السَّجْدَةَ مِنْ ذَلِكَ قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ وَيَرْكَعُ رَكْعَتَيْنِ قَبْلَ صَلاَةِ الْفَجْرِ ثُمَّ يَضْطَجِعُ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ لِلصَّلاَةِ  

Messenger of Allah ﷺ used to offer eleven rakʿat and that was his prayer. He used to prolong the prostration to such an extent that one could recite fifty verses (of the Qur'an) before he would lift his head. He used to pray two rakʿat (Sunna) before the Fajr prayer and then used to lie down on his right side till the call-maker came and informed him about the prayer.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي إِحْدَى عَشْرَةَ رَكْعَةً كَانَتْ تِلْكَ صَلاَتَهُ يَسْجُدُ السَّجْدَةَ مِنْ ذَلِكَ قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ وَيَرْكَعُ رَكْعَتَيْنِ قَبْلَ صَلاَةِ الْفَجْرِ ثُمَّ يَضْطَجِعُ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُنَادِي لِلصَّلاَةِ  

'A'isha, the wife of the Messenger of Allah ﷺ, said that between the time when the Messenger of Allah ﷺ finished the 'Isha' prayer which is called 'Atama by the people, he used to pray eleven rak'ahs, uttering the salutation at the end of every two rak'ahs, and observing the Witr with a single one. And when the Mu'adhdhin had finished the call (for the) dawn prayer and he saw the dawn clearly and the Mu'adhdhin had come to him, he stood up and prayed two short rak'ahs. Then he lay down on his right side till the Mu'adhdhin came to him for lqama. (This hadith has been narrated with the same chain of transmitters by Ibn Shihab, but in it no mention has been made of Iqama )  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي فِيمَا بَيْنَ أَنْ يَفْرُغَ مِنْ صَلاَةِ الْعِشَاءِ وَهِيَ الَّتِي يَدْعُو النَّاسُ الْعَتَمَةَ إِلَى الْفَجْرِ إِحْدَى عَشْرَةَ رَكْعَةً يُسَلِّمُ بَيْنَ كُلِّ رَكْعَتَيْنِ وَيُوتِرُ بِوَاحِدَةٍ فَإِذَا سَكَتَ الْمُؤَذِّنُ مِنْ صَلاَةِ الْفَجْرِ وَتَبَيَّنَ لَهُ الْفَجْرُ وَجَاءَهُ الْمُؤَذِّنُ قَامَ فَرَكَعَ رَكْعَتَيْنِ خَفِيفَتَيْنِ ثُمَّ اضْطَجَعَ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ لِلإِقَامَةِ وَحَدَّثَنِيهِ حَرْمَلَةُ أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ بِهَذَا الإِسْنَادِ وَسَاقَ حَرْمَلَةُ الْحَدِيثَ بِمِثْلِهِ غَيْرَ أَنَّهُ لَمْ يَذْكُرْ وَتَبَيَّنَ لَهُ الْفَجْرُ وَجَاءَهُ الْمُؤَذِّنُ وَلَمْ يَذْكُرِ الإِقَامَةَ وَسَائِرُ الْحَدِيثِ بِمِثْلِ حَدِيثِ عَمْرٍو سَوَاءً  

"The Messenger of Allah ﷺ used to pray eleven rak'ahs, making it odd (witr) by one between the time when he finished 'Isha and dawn, and he would prostrate for as long as it takes one of you to recite fifty verses before raising his head."

When the Mu'adhdhin finished the call to Fajr prayer and he could see the dawn, he would pray two brief Rak'ahs, then he would go out with him." Some of these narrators (Ibn Abi Dhi'b, Yunus and 'Amr bin Al-Harith) added some phrases not mentioned by the others in the Hadith.

It was narrated that ‘Aishah said, and this is the Hadith of Abu Bakr. “During the period after he finished the ‘Isha’ prayer until the Fajr, the Prophet ﷺ used to pray eleven Rak’ah, saying the Salam after each two Rak’ah and praying Witr with one Rak’ah. He would prostrate for as long as it takes anyone of you to recite fifty Verses before he would raise his head. When the Mu’adh-dhin fell silent after the first Adhan for the Subh prayer, he would get up and pray two brief Rak’ah.”

[Machine] The Messenger of Allah ﷺ used to pray eleven rak'ahs between the completion of 'Isha prayer, which is when people are called to the darkness of dawn, and the dawn prayer. In each set of two rak'ahs, he would recite the salaam. Additionally, he would perform one witr rak'ah. When the muezzin finished calling for the dawn prayer and the dawn appeared to him, and the muezzin came to him, he would stand and perform two light rak'ahs, then lie down on his right side until the muezzin came to him with the call to establish the prayer.

[Machine] Aisha, the wife of the Prophet ﷺ , said: The Prophet ﷺ used to pray eleven Rak'ahs (units of prayer) between the end of the night prayer (Isha) and the dawn prayer (Fajr). He would offer the Salaam (concluding the prayer) after every two Rak'ahs, and he would perform the Witr prayer (an odd-numbered prayer) with one Rak'ah. He would also make a long prostration, equivalent to reciting fifty verses of the Qur'an, before raising his head (from prostration). When the caller to prayer finishes the Fajr prayer and the dawn becomes clear to him, the Prophet ﷺ would get up and pray two light Rak'ahs, and then he would lie down on his right side until the caller to prayer comes to give the call for the Iqamah (the final announcement before prayer). He would then come out with the caller to prayer. Some of them add a little to this.

When the Mu'adhdhin finished the call to Fajr prayer and he could see the dawn, he would pray two brief Rak'ahs, then he would go out with him." Some of these narrators (Ibn Abi Dhi'b, Yunus and 'Amr bin Al-Harith) added some phrases not mentioned by the others in the Hadith. (Using translation from Nasāʾī 685)   

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ كَانَ النَّبِيُّ ﷺ يُصَلِّي فِيمَا بَيْنَ أَنْ يَفْرُغَ مِنْ صَلَاةِ الْعِشَاءِ إِلَى الْفَجْرِ إِحْدَى عَشْرَةَ رَكْعَةً يُسَلِّمُ مِنْ كُلِّ رَكْعَتَيْنِ وَيُوتِرُ بِوَاحِدَةٍ وَيَسْجُدُ سَجْدَةً قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ فَإِذَا سَكَتَ الْمُؤَذِّنُ مِنْ صَلَاةِ الْفَجْرِ وَتَبَيَّنَ لَهُ الْفَجْرُ قَامَ فَرَكَعَ رَكْعَتَيْنِ خَفِيفَتَيْنِ ثُمَّ اضْطَجَعَ عَلَى شِقِّهِ الْأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ لِلْإِقَامَةِ فَيَخْرُجَ مَعَهُ قَالَ وَبَعْضُهُمْ يَزِيدُ عَلَى بَعْضٍ فِي قِصَّةِ الْحَدِيثِ
