Musnad Ahmad

It is narrated from Hazrat Zaid bin Arqam (may Allah be pleased with him) that a Jewish man came to the service of the Holy Prophet (peace and blessings be upon him) and said, "O Abul Qasim! Do you not think that the people of Paradise will eat and drink in Paradise?" He had already told his friends that if the Holy Prophet (peace and blessings be upon him) affirmed this, then he would overpower him. The Holy Prophet (peace and blessings be upon him) said, "By Him in Whose hand is my soul, why not! Every person of Paradise will be given the strength of a hundred men in eating, drinking, desires, and intercourse." The Jew said, "Then will the one who eats and drinks also face the issue of relieving himself?" The Holy Prophet (peace and blessings be upon him) said, "The way of relieving themselves will be that they will sweat, which will flow from their skin, and from it will come the fragrance of musk, and their stomachs will become light."
