Machine translationRead the Arabic original
Question:
He says: Honorable Shaykh, may Allah grant you success. A man prayed 'Asr, then slept and did not wake up until the iqamah was being called. He went to the mosque and joined them in the prayer, thinking they were praying Maghrib. But when the imam stood for the fourth rak'ah, he realized they were praying 'Isha'. What should he do? Does he have an 'Isha' prayer?
Answer:
No, because he did not intend it. As for actions being by intentions, he did not intend 'Isha'; he intended Maghrib. So he has to pray Maghrib and pray 'Isha'. And he is, if Allah wills, excused for the sleep that he did not intend. Yes.
