Abu Musa reported Allah's Messenger (ﷺ) as saying:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بَرَّادٍ الأَشْعَرِيُّ ، وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا أَبُو أُسَامَةَ ، عَنْ بُرَيْدٍ ، عَنْ أَبِي بُرْدَةَ ، عَنْ أَبِي مُوسَى ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ أَعْظَمَ النَّاسِ أَجْرًا فِي الصَّلاَةِ أَبْعَدُهُمْ إِلَيْهَا مَمْشًى فَأَبْعَدُهُمْ وَالَّذِي يَنْتَظِرُ الصَّلاَةَ حَتَّى يُصَلِّيَهَا مَعَ الإِمَامِ أَعْظَمُ أَجْرًا مِنَ الَّذِي يُصَلِّيهَا ثُمَّ يَنَامُ " . وَفِي رِوَايَةِ أَبِي كُرَيْبٍ " حَتَّى يُصَلِّيَهَا مَعَ الإِمَامِ فِي جَمَاعَةٍ " .
The most eminent among human beings (as a recipient of) reward (is one) who lives farthest away, and who has to walk the farthest distance, and he who waits for the prayer to observe it along with the Imam, his reward is greater than one who prays (alone) and then goes to sleep. In the narration of Abu Kuraib (the words are):" (He waits) till he prays along with the Imam in congregation."
