The Ruling on Changing the Intention of an Obligatory Prayer Due to Forgetfulness

Question:
May Allah reward you. The questioner says: A person prayed Maghrib, and after finishing the prayer, it became clear to him that he had not prayed 'Asr. So he made the Maghrib prayer with the intention of 'Asr, and completed one rak'ah. After that, he prayed Maghrib. Is his prayer valid?

Answer:
No, the prayer is not valid. An obligatory prayer is not accepted if it is switched, and an obligatory prayer is not switched to another obligatory prayer. The obligatory prayer becomes invalid if you switch Maghrib to 'Asr; it becomes invalid, and neither 'Asr nor Maghrib is valid. This is not permissible. He should complete the prayer he is in because he is forgetful. As long as he is forgetful, the order is dropped due to the forgetfulness. He completes the prayer. When he has prayed Maghrib, he prays 'Asr after it. He is excused for that because he was forgetful.
