He missed some prayers during Ramadaan because he was asleep. What does he have to do?
Question

                During the month of fasting I feel so tired that if I sleep, I miss two or more obligatory prayers and I feel that I am sinning. My question is: If I sleep and miss Zuhr and ‘Asr until Maghrib comes, and I am afraid that the time for Maghrib is about to end, what should I do?.
Praise be to Allah.Not offering 
    the prayers at the proper time is a serious matter, concerning which Allaah 
    has issued a stern warning, as He says (interpretation of the meaning): 
“Then, 
    there has succeeded them a posterity who have given up As‑Salaah (the 
    prayers) [i.e. made their Salaah (prayers) to be lost, either by not 
    offering them or by not offering them perfectly or by not offering them in 
    their proper fixed times] and have followed lusts. So they will be thrown in 
    Hell”
[Maryam 
    19:59]
With regard 
    to what is meant by ghayy (translated here as “Hell”): 
Ibn 'Abbaas 
    (may Allaah be pleased with him) said: it means loss. Qataadah said it means 
    evil. ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) said it is a 
    valley in Hell that is very deep and its food is foul. 
See: 
    Tafseer Ibn Katheer (3/172). 
It was said 
    to Ibn Mas’ood (may Allaah be pleased with him): Allaah often mentions 
    prayer in the Qur’aan: “Except those who are devoted to Salaah (prayers)” 
    [al-Ma’aarij 70:23], “And those who strictly guard their (five 
    compulsory congregational) Salawaat (prayers) (at their fixed stated hours)” 
    [al-Mu’minoon 23:9, al-Ma’aarij 70:34], “So woe unto those performers 
    of Salaah (prayers) (hypocrites), Those who delay their Salaah (prayer from 
    their stated fixed times)” [al-Ma’oon 107:5]. He said: That warning is 
    about (not praying) on time. They said: O Abu ‘Abd al-Rahmaan, we thought it 
    was about not praying at all. He said: Not praying at all is kufr. 
Ta’zeem 
    Qadr al-Salaah by al-Marwazi (2/5). The editor 
    said its isnaad is hasan. 
The Prophet 
     (peace and blessings of Allaah be upon him) mentioned praying and 
    missing an obligatory prayer as being some of the reasons for which a person 
    will be punished in the grave. See the answer to question no.

    more about the horror and intensity of this punishment. We ask Allaah to 
    keep us safe and sound. 
There 
    follows an exhortation from the great Sahaabi ‘Abd-Allaah ibn Mas’ood (may 
    Allaah be pleased with him), in which he speaks eloquently of the ruling on 
    prayer in congregation, the situation of the one who fails to pray in 
    congregation, the reward of the one who goes to prayer, and the situation of 
    the one who is eager to go and stand in the row even though he is excused.  
He said:  
    “Whoever would like to meet Allaah, may He be exalted, tomorrow as a Muslim, 
    let him regularly offer these prayers where the call to prayer is given, for 
    Allaah has prescribed the Sunnahs of guidance to your Prophet (S) and they 
    (the prayers) are among the Sunnahs of guidance. If you pray in your houses 
    like this one who stays away from the mosque prays in his house, you will 
    have forsaken the Sunnah of your Prophet, and if you forsake the Sunnah of 
    your Prophet you will go astray.” [This is what he said about one who offers 
    the prayer on time, but he does not pray in congregation in the mosque, and 
    prays in his house. So what about one who does not pray until the time is 
    over altogether!] Then he said: There is no man who purifies himself and 
    purifies himself well, then he goes to one of these mosques, but Allaah will 
    record one good deed for him for every step he takes, and will raise him in 
    status one degree thereby, and will erase one bad deed thereby. I remember 
    when no one would stay away but a hypocrite whose hypocrisy was known, and a 
    man would come staggering between two others in order to stand in the row.  
    Narrated by Muslim (654). 
It is not 
    right for a Muslim to fast only in the month of Ramadaan. During the year 
    there are other virtuous days when it is mustahabb to fast, such as the day 
    of ‘Arafah and ‘Ashoora’. During the week it is mustahabb to fast on Mondays 
    and Thursdays. During every month it is mustahabb to fast three days of the 
    month. If you accustomed yourself to fasting all year round, you would not 
    experience such hardship that makes you sleep all day and miss the prayers. 
You have to 
    adopt the means that will wake you up for prayer. It is not permissible for 
    you to deliberately miss prayers on the basis of sleeping when you are able 
    to wake up at the time for prayer. 
You should 
    look at the reason why you are so tired when fasting. If it is because of 
    work, then you should weigh up work and fasting, and if you do not have to 
    work, and you cannot fast, pray and do other acts of worship because of 
    work, then you should take a leave of absence from work during the fasting 
    month. See the answer to question no. 
    65803 and 
    43772. If the reason is 
    staying up late at night, then it haraam for you to stay up late if that is 
    causing you to miss prayers until the time for them is over. 
You have to 
    advise your family members, wife and children to wake up for prayer, and 
    they have to help you to obey Allaah and offer the prayers on time. 
If you have 
    adopted the means and are still not able to wake up because of intense 
    tiredness or sickness, and the time for prayer has ended, then you must make 
    up the prayers that you have missed in the proper order. So you should pray 
    Zuhr and then ‘Asr and so on, unless you fear that the time for the second 
    prayer is about to end, in which case you should start with that. If you 
    wake up before the sun sets and you have not prayed Zuhr and ‘Asr, and so 
    little time is left for ‘Asr that the sun is about to set, then start with 
    ‘Asr, then pray Zuhr after that, then Maghrib. 
We ask 
    Allaah, may He be exalted, to help you to obey Him and worship Him well, and 
    to make you more keen to do good.
