[Machine] On the authority of the Prophet, ﷺ , he said: "One of the best prayers after the obligatory prayers is the prayer in the depths of the night. And indeed, the best fasting after the month of Ramadan is the fasting in the month of Allah that you call Al-Muharram." Ahmad ibn Al-Hasan Al-Qadi narrated to us, Hajib ibn Ahmad narrated to us, Muhammad ibn Mu'adh Al-Marwuzi narrated to us, Zakariya ibn Adi narrated to us, and he mentioned it.  

البيهقي:٤٦٦٢وَرَوَاهُ عُبَيْدُ اللهِ بْنُ عَمْرٍو الرَّقِّيُّ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ جُنْدُبِ بْنِ عَبْدِ اللهِ الْبَجَلِيِّ ؓ

عَنِ النَّبِيِّ ﷺ قَالَ مِنْ أَفْضَلِ الصَّلَاةِ بَعْدَ الْمَفْرُوضَةِ الصَّلَاةُ فِي جَوْفِ اللَّيْلِ وَإِنَّ أَفْضَلَ الصِّيَامِ بَعْدَ شَهْرِ رَمَضَانَ شَهْرُ اللهِ الَّذِي تَدْعُونَهُ الْمُحَرَّمَ أَخْبَرَنَاهُ أَحْمَدُ بْنُ الْحَسَنِ الْقَاضِي أنبأ حَاجِبُ بْنُ أَحْمَدَ أنبأ مُحَمَّدُ بْنُ مُعَاذٍ الْمَرُّوذِيُّ ثنا زَكَرِيَّا بْنُ عَدِيٍّ ثنا عُبَيْدُ اللهِ بْنُ عَمْرٍو فَذَكَرَهُ

"The Messenger of Allah ﷺ said: 'The best fasting after the month of Ramadan is the month of Allah, Al-Muharram, and the best prayer is prayer at night.'" (Using translation from Nasāʾī 1613)   

البيهقي:٨٤٢٤كَمَا أَخْبَرَنَا أَبُو أَحْمَدَ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ الْحَسَنِ الْمِهْرَجَانِيُّ الْعَدْلُ ثنا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عَبْدُوسٍ الْعَنَزِيُّ ثنا عُثْمَانُ بْنُ سَعِيدٍ الدَّارِمِيُّ ثنا الرَّبِيعُ بْنُ نَافِعٍ أَبُو تَوْبَةَ الْحَلَبِيُّ أَنَّ عُبَيْدَ اللهِ بْنَ عَمْرٍو حَدَّثَهُمْ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ جُنْدُبِ بْنِ سُفْيَانَ الْبَجَلِيِّ قَالَ

كَانَ النَّبِيُّ ﷺ يَقُولُ إِنَّ أَفْضَلَ الصَّلَاةِ بَعْدَ الْمَفْرُوضَةِ الصَّلَاةُ فِي جَوْفِ اللَّيْلِ وَإِنَّ أَفْضَلَ الصِّيَامِ بَعْدَ شَهْرِ رَمَضَانَ شَهْرُ اللهِ الَّذِي تَدْعُونَهُ الْمُحَرَّمَ
