Machine translationRead the Arabic original
Question:
The questioner says: I fasted on Thursday, and I had a missed fast to make up, but I did not intend during my fast that it was a make-up fast. Then, after the day ended, I intended that this fast would count as the make-up. Is it valid?
Answer:
It is not valid. The intention must be present at the beginning of the act. As for doing an act and then intending it after you are finished, that is not valid. Yes.
