A man prayed Maghrib without wudu' and did not remember until the time of 'Isha'?

The questioner : A man forgot a prayer and remembered it in the time of the prayer that follows it; for example, he forgot the Maghrib prayer, and the time for 'Isha' entered. So he started by praying Maghrib first, and then he prayed 'Isha'. In the second or third rak'ah of 'Isha', he remembered that he was not in a state of wudu'. So he performed wudu' here. Naturally, his intention was for 'Isha'. Does he complete 'Isha' and then go back to Maghrib, or does he pray Maghrib a second time? Or is it possible, given that he wants to follow the same sequence, that he prays Maghrib by building upon the two rak'ahs he has already prayed, completing the Maghrib prayer, and then enters into the 'Isha' prayer?

The Shaykh : When he prayed Maghrib, was he also... not in a state of wudu', but he was forgetting?

The questioner: Yes.

The Shaykh : And he did not remember this until the 'Isha' prayer.

The questioner: Yes.

The Shaykh : He only repeats it, or he only completes the 'Isha' prayer if wudu' is facilitated for him; otherwise, he returns... without the Maghrib obligatory prayer.

The questioner : Yes, if wudu' is facilitated for him, he only completes 'Isha'.

Another questioner : And Maghrib was [prayed] while he was forgetting...

The questioner : But it is within the same period, so he prays Maghrib... he does not repeat it.

The Shaykh: Yes.

The questioner : May Allah reward you with good.
