The enduring good deeds.
The reward for performing ablution well and praying two rak'ahs.
On the authority of 'Uqbah Ibn 'Amir al-Juhani, may Allah be pleased with him.
That the Messenger of Allah, peace and blessings of Allah be upon him, said:
"There is no one who performs ablution and perfects that ablution,
And then prays two rak'ahs,
Focusing his heart and his countenance upon them,
But that Paradise becomes mandatory for him."
Narrated by Abu Dawud.
