“In Sahih Muslim, it is recorded that `Umar bin Al-Khattab, may Allah be pleased with him, said, "The Messenger of Allah said: (There is no one among you who performs Wudu' and does it well, or -- amply --, then he says: "I testify that there is none worthy of worship except Allah and that Muhammad is His servant and Messenger, '' but the eight gates of Paradise will be opened for him and he will enter through whichever one he wishes.)”
