Sunan Abi Dawud, 176

Abbad b. Tamim reported from his uncle that a person made a complaint to the Prophet (ﷺ) that he entertained (doubt) as if something had happened to him which had rendered his ablution invalid. He (the Prophet) said:He should not cease (to pray) unless he hears a sound or perceives a smell (of passing wind)

Rapporté par Abbad b. Tamim, de la part de son oncle رضي الله عنه : Un homme s’est plaint au Prophète ﷺ en disant qu’il avait un doute, pensant que quelque chose avait annulé ses ablutions. Le Prophète ﷺ a dit : « Qu’il ne cesse pas de prier à moins d’entendre un son ou de sentir une odeur. »
