Narrated by Lady Aisha (may Allah be pleased with her), the honorable wife of the Messenger of Allah (ﷺ): She said, "When the Messenger of Allah (ﷺ) would pray, I would be lying in front of him, between him and the Qiblah, as an obstacle. When he intended to pray Witr, he would say: 'Move back a little.'"
