Is it permissible to complete the prayer and postpone asking about the ruling on a matter that arose during it until a later time, with the intention of asking about it and recording it?

If a worshiper doubts the invalidity of their prayer while performing it, they should not exit the prayer merely due to doubt. Rather, they should remain in it unless they become certain of its invalidity, especially if it is an obligatory prayer. This is because it is not permissible to interrupt it except for a valid legal reason, and due to Allah's saying: "And do not invalidate your deeds" (Quran 47:33). A Muslim should strive to learn what makes their prayer valid.
