It was narrated that Anas bin Malik said:“The Messenger of Allah (ﷺ) said: ‘A man’s prayer in his house is equal (in reward) to one prayer; his prayer in the mosque of the tribes is equal to twenty-five prayers; his prayer in the mosque in which Friday prayer is offered is equal to five-hundred prayers; his prayer in Aqsa Mosque is equal to fifty thousand prayers; his prayer in my mosque is equal to fifty thousand prayers; and his prayer in the Sacred Mosque is equal to one hundred thousand prayers.”
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا أَبُو الْخَطَّابِ الدِّمَشْقِيُّ، حَدَّثَنَا رُزَيْقٌ أَبُو عَبْدِ اللَّهِ الأَلْهَانِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " صَلاَةُ الرَّجُلِ فِي بَيْتِهِ بِصَلاَةٍ وَصَلاَتُهُ فِي مَسْجِدِ الْقَبَائِلِ بِخَمْسٍ وَعِشْرِينَ صَلاَةً وَصَلاَتُهُ فِي الْمَسْجِدِ الَّذِي يُجَمَّعُ فِيهِ بِخَمْسِمِائَةِ صَلاَةٍ وَصَلاَةٌ فِي الْمَسْجِدِ الأَقْصَى بِخَمْسِينَ أَلْفِ صَلاَةٍ وَصَلاَةٌ فِي مَسْجِدِي بِخَمْسِينَ أَلْفِ صَلاَةٍ وَصَلاَةٌ فِي الْمَسْجِدِ الْحَرَامِ بِمِائَةِ أَلْفِ صَلاَةٍ " .
