Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ عَلِيِّ بْنِ زَيْدٍ عَنْ أَبِي نَضْرَةَ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ الشَّيْطَانَ يَأْتِي أَحَدَكُمْ وَهُوَ فِي صَلَاتِهِ فَيَأْخُذُ بِشَعْرَةٍ مِنْ دُبُرِهِ فَيَمُدُّهَا فَيَرَى أَنَّهُ قَدْ أَحْدَثَ فَلَا يَنْصَرِفْ حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا.
English Translation
Affan told us, Hammad ibn Salamah told us, from Ali ibn Zayd, from Abu Nadrah, from Sa'id ibn al-Musayyab, from Abu Sa'id al-Khudri, that the Messenger of Allah (peace and blessings be upon him) said: "Indeed the devil comes to one of you while he is in his prayer and takes hold of a hair from his rear and pulls it, making him think that he has broken his ablution; so let him not leave [the prayer] until he hears a sound or perceives a smell."
