Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "The people of Paradise will eat and drink, but they will neither urinate nor defecate, nor will they bring forth phlegm, nor spit. Praise and glorification will be inspired in them just as breathing is inspired, and their food will be eliminated in the form of a burp, whose fragrance will be like that of musk."
