Yazid prayed along with the Messenger of Allah ﷺ when he was a young boy. When he (the Prophet) had prayed there were two persons (sitting) in the corner of the mosque; they did not pray (along with the Prophet). He called for them. They were brought trembling (before him). He asked: What prevented you from praying along with us? They replied: We have already prayed in our houses. He said: Do not do so. If any of you prays in his house and finds that the imam has not prayed, he should pray along with him; and that will be a supererogatory prayer for him.  

عَنْ أَبِيهِأَنَّهُ صَلَّى مَعَ رَسُولِ اللَّهِ ﷺ وَهُوَ غُلاَمٌ شَابٌّ فَلَمَّا صَلَّى إِذَا رَجُلاَنِ لَمْ يُصَلِّيَا فِي نَاحِيَةِ الْمَسْجِدِ فَدَعَا بِهِمَا فَجِيءَ بِهِمَا تُرْعَدُ فَرَائِصُهُمَا فَقَالَ مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَنَا قَالاَ قَدْ صَلَّيْنَا فِي رِحَالِنَا فَقَالَ لاَ تَفْعَلُوا إِذَا صَلَّى أَحَدُكُمْ فِي رَحْلِهِ ثُمَّ أَدْرَكَ الإِمَامَ وَلَمْ يُصَلِّ فَلْيُصَلِّ مَعَهُ فَإِنَّهَا لَهُ نَافِلَةٌ  

[Machine] The Messenger of Allah ﷺ prayed Fajr in Mina, then he turned and saw two men behind the people. So, he called them and they came to him trembling. He said, "What prevented you from praying with the people?" They said, "We had already prayed in our camp." He said, "Do not do so if one of you has prayed in his camp, and then he catches up with the prayer led by the imam, then he should still pray it with him, for it will be a voluntary prayer for him."  

صَلَّى رَسُولُ اللهِ ﷺ الْفَجْرَ بِمِنًى فَانْحَرَفَ فَرَأَى رَجُلَيْنِ مِنْ وَرَاءَ النَّاسِ فَدَعَا بِهِمَا فَجِيءَ بِهِمَا تَرْعَدُ فَرَائِصُهُمَا فَقَالَ مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَ النَّاسِ؟ فَقَالَا قَدْ كُنَّا صَلَّيْنَا فِي الرِّحَالِ قَالَ فَلَا تَفْعَلَا إِذَا صَلَّى أَحَدُكُمْ فِي رَحْلِهِ ثُمَّ أَدْرَكَ الصَّلَاةَ مَعَ الْإِمَامِ فَلْيُصَلِّهَا مَعَهُ فَإِنَّهَا لَهُنَافِلَةٌ

أَنَّهُ صَلَّى مَعَ رَسُولِ اللهِ ﷺ صَلَاةَ الصُّبْحِ بِمِنًى وَهُوَ غُلَامٌ شَابٌّ فَلَمَّا صَلَّى رَسُولُ اللهِ ﷺ إِذَا هُوَ بِرَجُلَيْنِ لَمْ يُصَلِّيَا فَدَعَا بِهِمَا فَجِيءَ بِهِمَا تَرْعَدُ فَرَائِصُهُمَا فَقَالَ لَهُمَا مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَنَا؟ قَالَا قَدْ صَلَّيْنَا فِي رِحَالِنَا قَالَ فَلَا تَفْعَلَا إِذَا صَلَّيْتُمْ فِي رِحَالِكُمْ ثُمَّ أَدْرَكْتُمُ الْإِمَامَ لَمْ يُصَلِّ فَصَلِّيَا مَعَهُ فَهِيَ لَكُمْ نَافِلَةٌ  

[Machine] I prayed with the Messenger of Allah ﷺ in Mina. When he finished the prayer, he noticed two men at the back of the people. He called them and said, "What prevented you from praying with the people?" They said, "O Messenger of Allah, we already prayed in our tents." He said, "Do not do so if any of you prays in his tent and then catches up with the congregation prayer, let him join them, as it will be a voluntary prayer for him."  

صَلَّيْتُ مَعَ رَسُولِ اللَّهِ ﷺ بِمِنًى فَلَمَّا سَلَّمَ أَبْصَرَ رَجُلَيْنِ فِي أَوَاخِرِ النَّاسِ فَدَعَاهُمَا فَقَالَ «مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَ النَّاسِ؟» فَقَالَا يَا رَسُولَ اللَّهِ صَلَّيْنَا فِي الرِّحَالِ قَالَ «فَلَا تَفْعَلَا إِذَا صَلَّى أَحَدُكُمْ فِي رَحْلِهِ ثُمَّ أَدْرَكَ الصَّلَاةَ مَعَ الْإِمَامِ فَلْيُصَلِّهَا مَعَهُ فَإِنَّهَا لَهُ نَافِلَةٌ»  

[Machine] "I prayed with the Messenger of Allah ﷺ in the morning in the Mosque of al-Khayf in Mina. When he finished, he faced the people and saw two men in the back of the crowd who did not pray with the people. He said, 'Bring these two men to me.' They were brought to him trembling. He asked them, 'What prevented you from praying with the people?' They said, 'O Messenger of Allah, we had already prayed in our tents.' He said, 'Do not do so when one of you has prayed in his tent and then catches the congregational prayer. He should pray it with them, for it will be a voluntary prayer for him.'"  

صَلَّيْتُ مَعَ رَسُولِ اللهِ ﷺ الْغَدَاةَ بِمِنًى فِي مَسْجِدِ الْخَيْفِ فَلَمَّا سَلَّمَ اسْتَقْبَلَ النَّاسَ بِوَجْهِهِ فَإِذَا هُو بِرَجُلَيْنِ فِي أُخْرَيَاتِ النَّاسِ لَمْ يُصَلِّيَا مَعَ النَّاسِ فَقَالَ ائْتُونِي بِهَذَيْنِ الرَّجُلَيْنِ فَأُتِيَ بِهِمَا تَرْعَدُ فَرَائِصُهُمَا فَقَالَ مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَ النَّاسِ قَالَا يَا رَسُولَ اللهِ قَد كُنَّا صَلَّيْنَا فِي الرِّحَالِ قَالَ لَا تَفْعَلَا إِذَا صَلَّى أَحَدُكُمْ فِي رَحْلِهِ وَأَدْرَكَ الصَّلَاةَ مَعَ النَّاسِ فَلْيُصَلِّهَا مَعَهُمْ فَإِنَّهَا لَه نَافِلَةٌ  

[Machine] We prayed Fajr with the Messenger of Allah ﷺ in Mina, then he turned and saw two men behind the people. He called them and they approached, trembling with fear. He asked them, "What prevented you from praying with the people?" They said, "O Messenger of Allah, we already prayed in our tents." He said, "Do not do that, if any one of you prays in his tent and then catches up with the imam, he should pray with the imam as it will be an optional prayer for him."  

صَلَّيْنَا مَعَ رَسُولِ اللهِ ﷺ الْفَجْرَ بِمِنًى فَانْحَرَفَ فَأَبْصَرَ رَجُلَيْنِ مِنْ وَرَاءِ النَّاسِ فَدَعَا بِهِمَا فَجِيءَ بِهِمَا تَرْعَدُ فَرَائِصُهُمَا فَقَالَ مَا مَنَعَكُمَا أَنْ تُصَلِّيَا مَعَ النَّاسِ؟ قَالَا يَا رَسُولَ اللهِ صَلَّيْنَا فِي الرَّحْلِ قَالَ لَا تَفْعَلُوا إِذَا صَلَّى أَحَدُكُمْ فِي رَحْلِهِ ثُمَّ أَدْرَكَ الصَّلَاةَ مَعَ الْإِمَامِ فَلْيُصَلِّهَا مَعَ الْإِمَامِ فَإِنَّهَا لَهُ نَافِلَةٌ هَكَذَا  

" صَلَّيْتُ مَعَ رَسُولِ اللهِ ﷺ الفَجْرَ، فَلَمَّا سَلَّمَ انْحَرفَ فَرَأى رَجُلَيْنِ مِنْ وَرَاءِ النَّاسِ فَدَعَاهُمْا فَجِئ بِهِما ترعدُ فَرَائِصُهُما فَقَالَ: مَا مَنَعكُمَا أَنْ تُصَلِّيا مَعَ النَّاسِ؟ قَالَا: يَا رَسُولَ اللهِ صَلَّيْنا فِى رِحَالِنَا، قَالَ: فَلَا تَفْعَلَا، إِذا صَلَّى أَحَدُكُمْ فِى رَحْلِهِ ثُمَ أدْرَكَ الصلاةَ مَعَ الإِمَام فَليُصَلِّهَا مَعَهُ فَإِنَهَا لَهُ نَافِلَة".  

"عَنْ يزِيدَ بْنِ الأَسْوَدِ قَالَ: حَجَجْتُ مَعَ رَسُولِ اللهِ ﷺ حَجةَ الوَداع، فَصَلِّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةَ الفَجْرِ، فَلَما صَلى اسْتَقْبَلَ الناسَ بِوَجْهِهِ فَإِذَا هُوَ بَرجُلَيْنِ فِى أُخْرَيَاتِ المَسْجِدِ لَمْ يُصَلِّيَا مَعَ الناسِ، فَقَالَ إئتُونِى بِهَذِيْنِ الرَّجُلَيْنِ قَالَ: مَا مَنَعَكُمَا أنْ تُصَليا مَعَ النَّاسِ؟ قَالَا: قَدْ صَلَّيْنَا فِى الرحالِ، قَالَ: فَلا تَفْعَلا، فَإِذَا صَلَّى أحَدُكُمْ فِى رَحْلِهِ ثُمَّ أدْرَكَ الصَّلاةَ فَلْيُصَلِّها مَعَهم فَإِنَّهَا نَافِلَةُ مَا بَقِىَ".
