What is the ruling on a fasting person sleeping through some of the prayers?

Question : The questioner says that a fasting person intended to fast, then ate a few hours before the pre-dawn meal, then slept. The call to the midday prayer was made while he was sleeping. What is the ruling on his fast?

Answer : If this sleep overcame him, and when he went to sleep before the call to the dawn prayer he intended to get up for the dawn prayer, but he was unable to do so, either because there was no one to wake him or because he could not, as some people cannot wake up if they sleep after staying up late, then he owes nothing. This is because the Prophet (peace and blessings be upon him) said: "Whoever sleeps through a prayer or forgets it, let him pray it when he remembers it." I do not mean by this to open a door for the lazy to enter through, but I say that some people may not wake up because there is no one to wake them, or because they are among those who, when they sleep, do not get up. Among the Companions (may Allah be pleased with them) were those who, when they slept, did not get up, such as Safwan ibn al-Ma'tal (may Allah be pleased with him). This is a matter in which people differ. In any case, if this happened without any negligence on his part, his fast is complete and he owes nothing. But if it was due to negligence on his part, such as if he always does this knowing that if he sleeps he will not get up, then it is forbidden for him and not permissible, and it is one of the things that diminishes his fast, due to the saying of the Prophet (peace and blessings be upon him) And what greater falsehood is there than a man who does not pray the prayer at its time or does not pray it with the Muslims? This is one of the greatest falsehoods. Therefore, we say to these people that they are making a great error, so they must repent to Allah, pray with the Muslims, and then sleep.
