Musnad Ahmad

Hazrat Aisha (may Allah be pleased with her) once learned that some people say that if a dog, a donkey, or a woman passes in front of someone praying, the prayer is invalidated. She said, "I think these people have equated us with dogs and donkeys. Sometimes the Prophet (peace and blessings be upon him) would pray at night, and I would be lying like a corpse between him and the Qiblah. If I needed something, I would slip away from the foot of the bed, because I did not like to pass in front of him."
