[Machine] The Messenger of Allah ﷺ said, "Whoever doubts whether he has performed a newly invented practice during his prayer should not leave until he hears a sound or finds a smell."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ خُيِّلَ لَهُ فِي صَلَاتِهِ أَنَّهُ قَدْ أَحْدَثَ فَلَا يَنْصَرِفَنَّ حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا»
