Evidence that if a person is certain that he is in a state of purity, then he doubts whether he has committed hadith (broken his wudu’), then he prays with his purity like that
وَحَدَّثَنِي عَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، قَالَ عَمْرٌو حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدٍ، وَعَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ، شُكِيَ إِلَى النَّبِيِّ صلى الله عليه وسلم الرَّجُلُ يُخَيَّلُ إِلَيْهِ أَنَّهُ يَجِدُ الشَّىْءَ فِي الصَّلاَةِ قَالَ " لاَ يَنْصَرِفُ حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا " . قَالَ أَبُو بَكْرٍ وَزُهَيْرُ بْنُ حَرْبٍ فِي رِوَايَتِهِمَا هُوَ عَبْدُ اللَّهِ بْنُ زَيْدٍ .
'Abbad b. Tamim reported from his uncle that a person made a complaint to the Apostle (ﷺ) 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.
