Changing the Intention from Qaḍā to Adā Prayer
Issue No.699- It is not permissible to change intention from qaḍā to adā (i.e., prayer offered within the prescribed time), nor from recommended to obligatory prayer. However, it is permissible to change one’s intention from adā to qaḍā. As a matter of fact, if the qaḍā prayer is the qaḍā of the prayer missed on the same day, the obligatory precaution is that one changes the intention from adā to qaḍā, and thereafter offers the adā prayer. Of course, this is only when it is possible to change the intention. For example, he can change his intention from ẓuhr prayer to qaḍā of fajr prayer only when he has not entered the third rak‘at of the ẓuhr prayer.
