Al-Aswad (may Allah have mercy on him) relates that someone said to Sayyidah Aishah (may Allah be pleased with her): "People say that a dog, a donkey and a woman (by passing in front) break the prayer." She said: "These people have made us equal to dogs and donkeys! Many times I saw the Messenger of Allah (peace and blessings be upon him) praying at night while I lay on the bed between him and the qiblah. If I had some need, I would quietly slip out from the foot of the bed, disliking to turn my face towards the Messenger of Allah (peace and blessings be upon him)."
