السابع: عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: مَنْ غَدَا إِلَى الْمَسْجِدِ أَوْ رَاحَ، أَعَدَّ اللَّهُ لَهُ فِي الْجَنَّةِ نُزُلاً كُلَّمَا غَدَا أَوْ رَاحَ ((مُتَّفَقٌ عَلَيْهِ)).
Abu Hurairah (May Allah be pleased with him) reported: The Prophet (ﷺ) said, "He who goes to the mosque at dawn or dusk (for Salat), Allah prepares a hospitable abode for him in Jannah, every time when he walks to it or comes back from it". [Al-Bukhari and Muslim].
