Narrated Zaid bin Thabit:

Allah's Apostle made a small room in the month of Ramadan (Sa'id said, "I think that Zaid bin Thabit said that it was made of a mat") and he prayed there for a few nights, and so some of his companions prayed behind him. When he came to know about it, he kept on sitting. In the morning, he went out to them and said, "I have seen and understood what you did. You should pray in your houses, for the best prayer of a person is that which he prays in his house except the compulsory prayers."

حَدَّثَنَا عَبْدُ الأَعْلَى بْنُ حَمَّادٍ، قَالَ حَدَّثَنَا وُهَيْبٌ، قَالَ حَدَّثَنَا مُوسَى بْنُ عُقْبَةَ، عَنْ سَالِمٍ أَبِي النَّضْرِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ زَيْدِ بْنِ ثَابِتٍ، أَنَّ رَسُولَ اللَّهِ ﷺ اتَّخَذَ حُجْرَةً ـ قَالَ حَسِبْتُ أَنَّهُ قَالَ ـ مِنْ حَصِيرٍ فِي رَمَضَانَ فَصَلَّى فِيهَا لَيَالِيَ، فَصَلَّى بِصَلاَتِهِ نَاسٌ مِنْ أَصْحَابِهِ، فَلَمَّا عَلِمَ بِهِمْ جَعَلَ يَقْعُدُ، فَخَرَجَ إِلَيْهِمْ فَقَالَ " قَدْ عَرَفْتُ الَّذِي رَأَيْتُ مِنْ صَنِيعِكُمْ، فَصَلُّوا أَيُّهَا النَّاسُ فِي بُيُوتِكُمْ، فَإِنَّ أَفْضَلَ الصَّلاَةِ صَلاَةُ الْمَرْءِ فِي بَيْتِهِ إِلاَّ الْمَكْتُوبَةَ ". قَالَ عَفَّانُ حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا مُوسَى، سَمِعْتُ أَبَا النَّضْرِ، عَنْ بُسْرٍ، عَنْ زَيْدٍ، عَنِ النَّبِيِّ ﷺ.
