What is the meaning of the hadith, "The worst of people are those who steal from their prayer," and how authentic is it?

Question:
My question to you, Honorable Shaykh, concerns a hadith I came across, but I do not know if it is authentic. It says that the worst thief is the one who steals from his prayer. Is this hadith authentic? And did they rule that shortening the pillars of the prayer carries the same ruling as theft, or something like that?

Answer:
Yes, this report is narrated from the Messenger of Allah (peace and blessings be upon him). There is some doubt about it. Yes, very well, that is enough. Listen to us, Muhammad, via the television. Please, Shaykh. Yes, it is established that the Messenger of Allah (peace and blessings be upon him) said, or it is reported from him that he said, "The worst of people are those who steal from their prayer." This is by lightening the bowing and prostration in it, and the tranquility in it, so that it becomes deficient. This is stealing from the prayer, and it is the worst kind of theft, worse than stealing money. People criticize those who steal people's money, and yes, that is a matter of blame, but worse than that is the one who steals from his prayer, so that he does not complete the bowing, the prostration, or the tranquility in it. Yes.
