The questioner : She says: One day I prayed 'Asr before the adhan, and I did not realize it because I was very anxious due to my illness. In the final tashahhud, I heard the adhan. Is my prayer valid, or must I repeat it? May Allah guide you?
The Shaykh : If the adhan was called at the beginning of the prayer time, then your prayer is not valid, and it is obligatory for you to repeat it. What you performed counts as a voluntary prayer, which increases your good deeds. However, if the mu'adhdhin delays the adhan after the time has entered and does not call it at the beginning, then your prayer is valid, provided you know or it is most likely in your mind that you prayed after the time had entered. However, since you are ill, it is permissible for you to combine the Zuhr and 'Asr prayers, and the Maghrib and 'Isha' prayers, if performing each prayer separately at its own time causes you hardship.
