What is the ruling on saying: "Depart — meaning, move away — from my sky"?

If this statement is uttered without justification, it contradicts ethics and good manners. However, if there is a justification for it, there is no sin in it, though refraining from it is better. There is no doctrinal prohibition in saying "my sky" (سمائي), because it is used to denote benefit, just as one might say "my land" (أرضي) or "our sky" (سمائنا) to indicate something that belongs to us.
