Sahih al-Bukhari, Hadith 2056 ⓘ

Narrated `Abbas bin Tamim: that his uncle said: "The Prophet was asked: If a person feels something during his prayer; should one interrupt his prayer?" The Prophet said: No! You should not give it up unless you hear a sound or smell something." Narrated Ibn Abi Hafsa: Az-Zuhri said, "There is no need of repeating ablution unless you detect a smell or hear a sound."

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ، قَالَ شُكِيَ إِلَى النَّبِيِّ صلى الله عليه وسلم الرَّجُلُ يَجِدُ فِي الصَّلاَةِ شَيْئًا، أَيَقْطَعُ الصَّلاَةَ قَالَ ‏ "‏ لاَ، حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا ‏" ‏‏.‏ وَقَالَ ابْنُ أَبِي حَفْصَةَ عَنِ الزُّهْرِيِّ لاَ وُضُوءَ إِلاَّ فِيمَا وَجَدْتَ الرِّيحَ أَوْ سَمِعْتَ الصَّوْتَ‏.‏
