To ask forgiveness for s.t.; say the confession of faith; utter an Arabic phrase (as an expression of dismay).
Tawubat is in most cases understood as the pronouncing of certain Arabic phrases during a prayer ceremony. People at the point of death are also urged to pronounce them. In order to clear one’s mind of bad feelings one may say parts of those phrases. Often if something goes wrong, breaks or at bad news people say: astag! or: astag pirulla!
I regret and ask forgiveness because of my sins.
If someone has made you angry say the statement of faith so that your anger will leave.
I happened to exclaim when I arrived and a rat had eaten my blouse. (I said: astag pirulla.)
