What is the ruling on saying "your Lord's money" without intention or thought?

Uttering the word "Rabbuk" (your Lord) intending Allah Almighty is a reprehensible and odious statement, and its utterer must repent sincerely. It diminishes Allah, Glorified be His Name, and its ruling is known. The ruling does not differ between someone serious and someone joking, due to the Almighty's saying: "And if you ask them, they will surely say, 'We were only conversing and playing.' Say, 'Is it with Allah and His verses and His Messenger that you were mocking?' Make no excuse; you have disbelieved after your belief."

However, if it slips from the tongue unintentionally, or if one's mind is absent due to intense anger, there is no sin; due to the Almighty's saying: "And there is no blame upon you for that in which you have erred, but [only for] what your hearts intended."

If "Rabb" is intended to mean master or owner, the word is not as heinous, but it should still be avoided due to the reprehensible implication it might convey.
