Full Sharh — Riyad as-Salihin 1201
وعن جابر رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : “يأكل أهل الجنة فيها ، ويشربون ، ولا يتغوطون، ولا يتمخطون، ولا يبولون، ولكن طعامهم ذلك جشاء كرشح المسك، يلهمون التسبيح والتكبير، كما يلهمون النفس" ((رواه مسلم)).
English Translation
Jabir (May Allah be pleased with him) reported:: 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.".
