When is the Sunnah of Fajr made up for the one who missed it?

Well, in his third and final question, he says: If a worshipper is unable to pray the Sunnah of the Fajr prayer due to the tightness of time, is it obligatory to pray it after the obligatory prayer? We thank you...?
Answer: If he is praying alone or is the imam and he is able to pray the regular voluntary prayer, he prays it before the obligatory prayer. As for if, for example, the follower missed the obligatory prayer, or if he arrived and the imam had already called for the prayer to begin, he joins them in the prayer and then prays it after the prayer. He prays the regular voluntary prayer after the prayer. If he wishes, he may delay it until the sun has risen. All of this is established by the Sunnah. The best is to delay it until the sun has risen, but one may fear forgetting it. So if he prays it after the prayer, the Sunnah of Fajr, there is no harm. It is established that he (peace and blessings be upon him) saw a man praying after Fajr and said: The man said: O Messenger of Allah! It is the Sunnah of Fajr which I did not pray before. So he (peace and blessings be upon him) remained silent regarding him. The hadith is acceptable. And it is established from him (peace and blessings be upon him) the command to delay it until after the sun has risen. So all of this is Sunnah. If he prays it after the prayer, there is no harm so that he does not forget it. And if he delays it and prays it after the sun has risen, there is no harm. It is all good.
The presenter: Yes. This message came from the listener 'Abd al-Karim from al-Khafji, asking...
The Shaykh: I have something here that should be pointed out, and that is that a person may sleep and not wake up until near the sun. In this case, he prays the regular voluntary prayer first. Even if he is (one who stays up late), like a person who is overcome by sleep and did not hear the clock or has no one to wake him, and he gets up and has missed the time, meaning he has missed the congregation, he prays the regular voluntary prayer even if it is after the sun has risen. If he did not get up until after the sun had risen, he prays the Sunnah of two rak'ahs first, then he prays Fajr. This is how it was when the Prophet (peace and blessings be upon him) slept through the Fajr prayer on some of his journeys and did not wake up until after the sun. He (peace and blessings be upon him) got up, so he ordered Bilal to call the adhan and he prayed as he does every day (peace and blessings be upon him). He prayed the regular voluntary prayer and then prayed the obligatory prayer with the people. This is the Sunnah. If the sleeper wakes up and has missed the congregational prayer, or wakes up after the sun has risen, he prays in his original state. He prays the Sunnah of Fajr first, then he prays the obligatory prayer, and he does not delay the Sunnah. Yes.
