Prayer
Mosques and places of Prayer - Section 1
وَعَنْ أَبِي مُوسَى الْأَشْعَرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَعْظَمُ النَّاسِ أَجْرًا فِي الصَّلَاةِ أَبْعَدُهُمْ فَأَبْعَدُهُمْ مَمْشًى وَالَّذِي يَنْتَظِرُ الصَّلَاةَ حَتَّى يُصَلِّيَهَا مَعَ الْإِمَامِ أَعْظَمُ أجرا من الَّذِي يُصَلِّي ثمَّ ينَام»
Abu Musa reported God’s Messenger as saying, “The one who will receive the greatest reward for prayer is he who lives farthest away, and he who has farthest to walk and he who waits for the prayer to observe it with the imam will have a greater reward than the one who observes it and then goes to sleep.” (Bukhari and Muslim.)
