What did the Prophet Muhammad (peace be upon him) direct a person to do if they suspected something broke their ablution during prayer?
 'Abbad b. Tamim reported from his uncle that a person made a complaint to the Apostle (may peace be upon him) that he entertained (doubt) as it 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 and Zuhair b. Harb have pointed out in their narrations that it was 'Abdullah b. Zaid.
