Sayyiduna Abu Qatadah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "The worst of people in terms of theft is the one who steals from his prayer." It was asked: O Messenger of Allah! How can someone steal from his prayer? He said: "By not performing the bowing (ruku') and prostration (sujud) properly (correctly)."
