Narrated `Abbad bin Tamim: My uncle said: The Prophet said, "One should not leave his prayer unless he hears sound or smells something."
حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ عَبَّادِ بْنِ تَمِيمٍ، عَنْ عَمِّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ يَنْصَرِفْ حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا " .
