Sahih Muslim Book - 5, Hadith - 1513

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بَرَّادٍ الأَشْعَرِىُّ وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ بُرَيْدٍ عَنْ أَبِى بُرْدَةَ عَنْ أَبِى مُوسَى قَالَ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « إِنَّ أَعْظَمَ النَّاسِ أَجْرًا فِى الصَّلاَةِ أَبْعَدُهُمْ إِلَيْهَا مَمْشًى فَأَبْعَدُهُمْ وَالَّذِى يَنْتَظِرُ الصَّلاَةَ حَتَّى يُصَلِّيَهَا مَعَ الإِمَامِ أَعْظَمُ أَجْرًا مِنَ الَّذِى يُصَلِّيهَا ثُمَّ يَنَامُ ». وَفِى رِوَايَةِ أَبِى كُرَيْبٍ « حَتَّى يُصَلِّيَهَا مَعَ الإِمَامِ فِى جَمَاعَةٍ ».

It was narrated that Abu Musa said: "The Messenger of Allah (s.a.w) said: 'The people who will have the greatest reward for prayer will be those who walk the furthest distance to come and pray, then those who walk the next furthest. The one who waits for the prayer until he prays with the Imam will have a greater reward than the one who prays then sleeps." According to the report of Ibn Kuraib: "until he prays it with the Imam in congregation."
