The ruling on one who wakes up in a state of major ritual impurity during the day of Ramadan

Question:
The questioner is from Sudan, and he says in this question: A man had intercourse with his wife on the night of Ramadan, then he slept before taking the full ritual bath, and he did not wake up for the Fajr prayer. He remained asleep until Dhuhr, still in a state of major ritual impurity. Then he got up, took the full ritual bath, and prayed Dhuhr. What is required of him? And is his fast for that day permissible?

Answer:
Yes, his fast is valid. If the intercourse was at night, his fast is valid. However, he erred in not managing his affairs by setting an alarm to wake him up for the dawn, or before the dawn, or by asking one of his family members to wake him. It is obligatory for him, when he wakes up, to hasten to pray Fajr: he should take the full ritual bath and pray Fajr, then pray Dhuhr in its time until the end of it.
So the result is: he is negligent and careless, and his fast is valid if he intended to fast; his fast is valid even if he slept until Dhuhr. But he must repent to Allah for his carelessness. When he gets up, he should take the full ritual bath and pray Fajr, whether he woke up at the time of the morning sun or at Dhuhr, he prays Fajr, then prays the other prayer after it. Yes.
