حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدِ بْنِ عَبْدِ اللَّهِ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " أَعْظَمُ النَّاسِ أَجْرًا فِي الصَّلاَةِ أَبْعَدُهُمْ فَأَبْعَدُهُمْ مَمْشًى، وَالَّذِي يَنْتَظِرُ الصَّلاَةَ حَتَّى يُصَلِّيَهَا مَعَ الإِمَامِ أَعْظَمُ أَجْرًا مِنَ الَّذِي يُصَلِّي ثُمَّ يَنَامُ ".
English translation
Narrated Abu Musa:The Prophet (ﷺ) said, "The people who get tremendous reward for the prayer are those who are farthest away (from the mosque) and then those who are next farthest and so on. Similarly one who waits to pray with the Imam has greater reward than one who prays and goes to bed
