(19) باب لُزُومِ الْمَسَاجِدِ وَانْتِظَارِ الصَّلاَةِ
It was narrated from Abu Hurairah that:
The Prophet 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."
