'Abbad bin Tamim reported from his uncle that a person made a complaint to the Apostle (ﷺ) that he entertained (doubt) as if something had happened to him breaking his ablution. He (the Holy Prophet) said: He should not return (from prayer) unless he hears a sound or perceives a smell (of passing wind). Abu Bakr (RA) and Zuhair bin Harb have pointed out in their narrations that it was 'Abdullah bin Zaid.
