Narrated Abu Musa:

My companions, who came with me in the boat and I landed at a place called Baqi Buthan. The Prophet was in Medina at that time. One of us used to go to the Prophet by turns every night at the time of the Isha prayer. Once I along with my companions went to the Prophet and he was busy in some of his affairs, so the 'Isha' prayer was delayed to the middle of the night He then came out and led the people (in prayer). After finishing from the prayer, he addressed the people present there saying, "Be patient! Don't go away. Have the glad tiding. It is from the blessing of Allah upon you that none amongst mankind has prayed at this time save you." Or said, "None except you has prayed at this time." Abu Muisa added, 'So we returned happily after what we heard from Alllah's Apostle ."

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ أَخْبَرَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدٍ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ كُنْتُ أَنَا وَأَصْحَابِي الَّذِينَ، قَدِمُوا مَعِي فِي السَّفِينَةِ نُزُولاً فِي بَقِيعِ بُطْحَانَ، وَالنَّبِيُّ ﷺ بِالْمَدِينَةِ، فَكَانَ يَتَنَاوَبُ النَّبِيَّ ﷺ عِنْدَ صَلاَةِ الْعِشَاءِ كُلَّ لَيْلَةٍ نَفَرٌ مِنْهُمْ، فَوَافَقْنَا النَّبِيَّ ـ عليه السلام ـ أَنَا وَأَصْحَابِي وَلَهُ بَعْضُ الشُّغْلِ فِي بَعْضِ أَمْرِهِ فَأَعْتَمَ بِالصَّلاَةِ حَتَّى ابْهَارَّ اللَّيْلُ، ثُمَّ خَرَجَ النَّبِيُّ ﷺ فَصَلَّى بِهِمْ، فَلَمَّا قَضَى صَلاَتَهُ قَالَ لِمَنْ حَضَرَهُ " عَلَى رِسْلِكُمْ، أَبْشِرُوا إِنَّ مِنْ نِعْمَةِ اللَّهِ عَلَيْكُمْ أَنَّهُ لَيْسَ أَحَدٌ مِنَ النَّاسِ يُصَلِّي هَذِهِ السَّاعَةَ غَيْرُكُمْ ". أَوْ قَالَ " مَا صَلَّى هَذِهِ السَّاعَةَ أَحَدٌ غَيْرُكُمْ ". لاَ يَدْرِي أَىَّ الْكَلِمَتَيْنِ قَالَ. قَالَ أَبُو مُوسَى فَرَجَعْنَا فَفَرِحْنَا بِمَا سَمِعْنَا مِنْ رَسُولِ اللَّهِ ﷺ.
