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  

Between the time when the Messenger of Allah ﷺ finished the night prayer till the dawn broke, he used to pray eleven rak'ahs, uttering the salutation at the end of every two and observing the witr with a single one, and during that he would make a prostration about as long a one of you would take to recite fifty verses before raising his head. When the mu'adhdhin finished making the call for the dawn prayer, he stood up and prayed two short rak'ahs, then he lay down on his right side till the mu'adhdhin came to him  

كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي فِيمَا بَيْنَ أَنْ يَفْرُغَ مِنْ صَلاَةِ الْعِشَاءِ إِلَى أَنْ يَنْصَدِعَ الْفَجْرُ إِحْدَى عَشْرَةَ رَكْعَةً يُسَلِّمُ مِنْ كُلِّ ثِنْتَيْنِ وَيُوتِرُ بِوَاحِدَةٍ وَيَمْكُثُ فِي سُجُودِهِ قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ فَإِذَا سَكَتَ الْمُؤَذِّنُ بِالأُولَى مِنْ صَلاَةِ الْفَجْرِ قَامَ فَرَكَعَ رَكْعَتَيْنِ خَفِيفَتَيْنِ ثُمَّ اضْطَجَعَ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ
