The enduring good deeds.
The reward for performing the Isha and Fajr prayers in congregation.
Uthman Ibn Affan entered the mosque after the Maghrib prayer.
He sat down alone, so I sat beside him.
He said, "O son of my brother,
I heard the Messenger of Allah, peace and blessings of Allah be upon him, say:
'Whoever performs the Isha prayer in congregation,
it is as if he had spent half the night in prayer;
and whoever performs the Fajr prayer in congregation,
it is as if he had prayed the entire night.'"
Recorded by Muslim.
