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."
