Sahih al-Bukhari 514
Sahih al-Bukhari · Book 8: Prayers (Salat) · Whoever says "Nothing annuls As-Salat (the prayer) (i.e. nothing of what others do, not the praying person himself)."
Narrated `Aisha:
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ ، قَالَ حَدَّثَنَا إِبْرَاهِيمُ ، عَنِ الأَسْوَدِ ، عَنْ عَائِشَةَ ،. قَالَ الأَعْمَشُ وَحَدَّثَنِي مُسْلِمٌ ، عَنْ مَسْرُوقٍ ، عَنْ عَائِشَةَ ، ذُكِرَ عِنْدَهَا مَا يَقْطَعُ الصَّلاَةَ الْكَلْبُ وَالْحِمَارُ وَالْمَرْأَةُ فَقَالَتْ شَبَّهْتُمُونَا بِالْحُمُرِ وَالْكِلاَبِ، وَاللَّهِ لَقَدْ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يُصَلِّي، وَإِنِّي عَلَى السَّرِيرِ ـ بَيْنَهُ وَبَيْنَ الْقِبْلَةِ ـ مُضْطَجِعَةً فَتَبْدُو لِي الْحَاجَةُ، فَأَكْرَهُ أَنْ أَجْلِسَ فَأُوذِيَ النَّبِيَّ صلى الله عليه وسلم فَأَنْسَلُّ مِنْ عِنْدِ رِجْلَيْهِ.
The things which annul prayer were mentioned before me (and those were): a dog, a donkey and a woman. I said, "You have compared us (women) to donkeys and dogs. By Allah! I saw the Prophet (ﷺ) praying while I used to lie in (my) bed between him and the Qibla. Whenever I was in need of something, I disliked to sit and trouble the Prophet. So, I would slip away by the side of his feet."
