Sahih Muslim Book - 5, Hadith - 1451

وَحَدَّثَنَا أَبُو عَامِرٍ الأَشْعَرِىُّ وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ بُرَيْدٍ عَنْ أَبِى بُرْدَةَ عَنْ أَبِى مُوسَى قَالَ كُنْتُ أَنَا وَأَصْحَابِى الَّذِينَ قَدِمُوا مَعِى فِى السَّفِينَةِ نُزُولاً فِى بَقِيعِ بُطْحَانَ وَرَسُولُ اللَّهِ -صلى الله عليه وسلم- بِالْمَدِينَةِ فَكَانَ يَتَنَاوَبُ رَسُولَ اللَّهِ -صلى الله عليه وسلم- عِنْدَ صَلاَةِ الْعِشَاءِ كُلَّ لَيْلَةٍ نَفَرٌ مِنْهُمْ قَالَ أَبُو مُوسَى فَوَافَقْنَا رَسُولَ اللَّهِ -صلى الله عليه وسلم- أَنَا وَأَصْحَابِى وَلَهُ بَعْضُ الشُّغُلِ فِى أَمْرِهِ حَتَّى أَعْتَمَ بِالصَّلاَةِ حَتَّى ابْهَارَّ اللَّيْلُ ثُمَّ خَرَجَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَصَلَّى بِهِمْ فَلَمَّا قَضَى صَلاَتَهُ قَالَ لِمَنْ حَضَرَهُ « عَلَى رِسْلِكُمْ أُعْلِمُكُمْ وَأَبْشِرُوا أَنَّ مِنْ نِعْمَةِ اللَّهِ عَلَيْكُمْ أَنَّهُ لَيْسَ مِنَ النَّاسِ أَحَدٌ يُصَلِّى هَذِهِ السَّاعَةَ غَيْرُكُمْ ». أَوْ قَالَ « مَا صَلَّى هَذِهِ السَّاعَةَ أَحَدٌ غَيْرُكُمْ ». لاَ نَدْرِى أَىَّ الْكَلِمَتَيْنِ قَالَ قَالَ أَبُو مُوسَى فَرَجَعْنَا فَرِحِينَ بِمَا سَمِعْنَا مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم-.

It was narrated that Abu Musa said: "My companions and I - who came with me in the ship - were staying in the valley of Buthan, and the Messenger of Allah (s.a.w) was in Al-Madinah. Every night it would be the turn of a group of them to go to the Messenger of Allah (s.a.w) at the time of 'Isha' prayer." Abu Musa said: "My companions and I went to the Messenger of Allah (s.a.w), but something kept him busy until he prayed while it was very dark, almost halfway through the night. Then the Messenger of Allah (s.a.w) came out and led them in prayer, and when he had finished his prayer he said to those who were present: 'Wait! I will tell you something and give you glad tidings. It is Allah's blessing to you that no one else among the people is praying at this hour except you."' Abu Musa said: "We went back rejoicing at what we had heard from the Messenger of Allah (s.a.w)."
