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

كَانَ النَّبِيُّ ﷺ إِذَا صَلَّى صَلاَةً أَقْبَلَ عَلَيْنَا بِوَجْهِهِ

The Messenger of Allah ﷺ led us in the Fajr prayer at al-Hudaybiyah after rainfall that had fallen during the night. When he finished, he turned to the people and said: “Do you know what your Lord has said?” They said: “Allah and His Messenger know best.” He said: “This morning some of My servants have become believers in Me and disbelievers: as for the one who says, ‘We have been given rain by Allah’s favor and mercy,’ that one is a believer in Me and a disbeliever in the star; but as for the one who says, ‘We have been given rain by such-and-such a star,’ that one is a disbeliever in Me and a believer in the 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
