Sunan Ibn Majah, 800
sahih· Darussalam

It was narrated from Abu Hurairah that:

The Prophet (ﷺ) said: "A muslim does not regularly attend the mosques to perform prayer and remember Allah, but Allah feels happy with him just as the family of one who is absent feels happy when he comes back to them."

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَبَابَةُ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنِ الْمَقْبُرِيِّ، عَنْ سَعِيدِ بْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏

‏ مَا تَوَطَّنَ رَجُلٌ مُسْلِمٌ الْمَسَاجِدَ لِلصَّلاَةِ وَالذِّكْرِ إِلاَّ تَبَشْبَشَ اللَّهُ لَهُ كَمَا يَتَبَشْبَشُ أَهْلُ الْغَائِبِ بِغَائِبِهِمْ إِذَا قَدِمَ عَلَيْهِمْ ‏

‏ ‏.‏
