The Prophet ﷺ used to face us on completion of the prayer.  

كَانَ النَّبِيُّ ﷺ إِذَا صَلَّى صَلاَةً أَقْبَلَ عَلَيْنَا بِوَجْهِهِ  

The Prophet ﷺ led us in the Fajr prayer at Hudaibiya after a rainy night. On completion of the prayer, he faced the people and said, "Do you know what your Lord has said (revealed)?" The people replied, "Allah and His Apostle know better." He said, "Allah has said, 'In this morning some of my slaves remained as true believers and some became non-believers; whoever said that the rain was due to the Blessings and the Mercy of Allah had belief in Me and he disbelieves in the stars, and whoever said that it rained because of a particular star had no belief in Me but believes in that star.' "  

صَلَّى لَنَا رَسُولُ اللَّهِ ﷺ صَلاَةَ الصُّبْحِ بِالْحُدَيْبِيَةِ عَلَى إِثْرِ سَمَاءٍ كَانَتْ مِنَ اللَّيْلَةِ۔ فَلَمَّا انْصَرَفَ أَقْبَلَ عَلَى النَّاسِ فَقَالَ: «هَلْ تَدْرُونَ مَاذَا قَالَ رَبُّكُمْ؟» قَالُوا: اللَّهُ وَرَسُولُهُ أَعْلَمُ۔ قَالَ: «أَصْبَحَ مِنْ عِبَادِي مُؤْمِنٌ بِي وَكَافِرٌ: فَأَمَّا مَنْ قَالَ مُطِرْنَا بِفَضْلِ اللَّهِ وَرَحْمَتِهِ فَذَلِكَ مُؤْمِنٌ بِي وَكَافِرٌ بِالْكَوْكَبِ، وَأَمَّا مَنْ قَالَ بِنَوْءِ كَذَا وَكَذَا فَذَلِكَ كَافِرٌ بِي وَمُؤْمِنٌ بِالْكَوْكَبِ۔»  

Once the Prophet ﷺ delayed the ʿIsha' prayer until midnight and then came to us. Having prayed he faced us and said, "The people had prayed and slept but you were in the prayer as long as you were waiting for it."  

أَخَّرَ رَسُولُ اللَّهِ ﷺ الصَّلاَةَ ذَاتَ لَيْلَةٍ إِلَى شَطْرِ اللَّيْلِ ثُمَّ خَرَجَ عَلَيْنَا فَلَمَّا صَلَّى أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ إِنَّ النَّاسَ قَدْ صَلَّوْا وَرَقَدُوا وَإِنَّكُمْ لَنْ تَزَالُوا فِي صَلاَةٍ مَا انْتَظَرْتُمُ الصَّلاَةَ
