The enduring good deeds.
The reward for performing wudu thoroughly and the dhikr that follows it.
On the authority of 'Umar ibn al-Khattab, may Allah be pleased with him, who said:
The Messenger of Allah, peace and blessings of Allah be upon him, said:
"There is not one of you who performs wudu,
and does so completely or thoroughly,
then says:
'I bear witness that there is no god but Allah,
and that Muhammad is the servant of Allah and His Messenger,'
but that the eight gates of Paradise will be opened for him,
so that he may enter through whichever of them he wishes."
