Masruq (may Allah have mercy on him) narrates that in the presence of Sayyida Aisha (may Allah be pleased with her), mention was made of those things which invalidate the prayer, namely a dog, a donkey, and a woman. Upon this, Sayyida Aisha (may Allah be pleased with her) said, "You have equated us with donkeys and dogs! By Allah, the Prophet (peace and blessings of Allah be upon him) used to pray while I would be lying on the bed between him and the Qiblah. If I needed something, and since I did not like to sit up in front of him (while he was praying) and thus cause him discomfort, I would quietly slip away from the side of his feet."
