The enduring good deeds.
The reward for performing wudu perfectly and praying in congregation.
On the authority of 'Uthman ibn 'Affan, may Allah be pleased with him, who said:
I heard the Messenger of Allah, peace and blessings of Allah be upon him, say:
Whoever performs wudu for prayer and does so perfectly,
Then walks to the prescribed prayer,
And performs it with the people, or with the congregation, or in the mosque,
Allah will forgive his sins.
