It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed the worst thief among people is the one who steals from his prayer." It was said: "O Messenger of Allah, how does he steal from his prayer?" He (peace and blessings be upon him) said: "He does not complete its bowings and its prostrations. And the most miserly of people is the one who is miserly with the greeting of salam."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abdullah (may Allah be pleased with him) except al-Hasan (may Allah have mercy on him), nor from al-Hasan except Awf, nor from Awf except Uthman, and Zayd is alone in narrating it."
