The Messenger of Allah (ﷺ) said, "The inhabitants of Jannah will eat and drink therein, but they will not have to pass excrement, to blow their noses or to urinate. Their food will be digested producing belch which will give out a smell like that of musk. They will be inspired to declare the freedom of Allah from imperfection and proclaim His Greatness as easily as you breathe."
