Sahih Bukhari Volume 7, Book 77, Hadith 5863

حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي بَكْرٍ، حَدَّثَنَا مُعْتَمِرٌ، عَنْ عُبَيْدِ اللَّهِ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَحْتَجِرُ حَصِيرًا بِاللَّيْلِ فَيُصَلِّي، وَيَبْسُطُهُ بِالنَّهَارِ فَيَجْلِسُ عَلَيْهِ، فَجَعَلَ النَّاسُ يَثُوبُونَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَيُصَلُّونَ بِصَلاَتِهِ حَتَّى كَثُرُوا فَأَقْبَلَ فَقَالَ ‏"‏ يَا أَيُّهَا النَّاسُ خُذُوا مِنَ الأَعْمَالِ مَا تُطِيقُونَ، فَإِنَّ اللَّهَ لاَ يَمَلُّ حَتَّى تَمَلُّوا، وَإِنَّ أَحَبَّ الأَعْمَالِ إِلَى اللَّهِ مَا دَامَ وَإِنْ قَلَّ ‏"‏‏

Narrated By 'Aisha : The Prophet used to construct a loom with a Hasir at night m order to pray therein, and during the day he used to spread it out and sit on it. The people started coming to the Prophet at night to offer the prayer behind him When their number increased, the Prophet faced them and said. O people! Do only those good deeds which you can do, for Allah does not get tired (of giving reward) till you get tired, and the best deeds to Allah are the incessant ones though they were few."
