The enduring good deeds,
the enduring righteous deeds:
The reward of consistently performing the prayers in congregation.
On the authority of 'Abdullah Ibn Mas'ud (may Allah be pleased with him), who said:
"Whoever would be pleased to meet Allah tomorrow as a Muslim,
let him consistently preserve these prayers wherever the call to them is made;
for Allah has legislated for your Prophet (peace and blessings of Allah be upon him) the ways of guidance,
and they are indeed among the ways of guidance."
This hadith was narrated by Muslim.
