It is narrated from the wife of the Prophet, Sayyida Aisha (may Allah be pleased with her), that I used to sleep in front of the Prophet (peace be upon him) and my feet would be towards his qiblah. Then when the Prophet (peace be upon him) would go into prostration, he would touch my feet with his hand, and I would withdraw my feet. Then when he stood up, I would stretch out my feet again. In those days, there were no lamps in the houses.
