I want to know that do you always have to listen to your parents. I am a 16 year old and would rather prefer to stay up and pray fajr rather than wake up after and 99% of the time i do not wake up, infact i mostly wake up about 10 even if i go sleep early- the same time i would wake up if i stayed up til fajr salaah. As i have holidays i would love to do it but my parents do not let me stay up, even though they know the reason why i am staying up. What should i do. I feel like ignoring them sometimes and just staying up.

Praise
be to Allah

Obedience to parents is obligatory upon the child with regard
to that which will benefit them and will not cause him any harm. But if
there is no benefit for them in it, or it will harm the child, then he is
not obliged to obey them in that case.

Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him)
said in al-Ikhtiyaaraat (p. 114): The individual is obliged to obey
his parents so long as it does not involve any sin, even if they are
evildoers… This applies to that which is beneficial for them and is not
harmful for him. End quote.

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:

If they say to him: Do not eat this food, do not eat meat, do
not eat rice, do not eat a certain thing – and it is something that he wants
to eat – then he is not obliged to obey them in that, because it does not
serve any interest for them, and it is harmful for him because it causes him
to miss out on something that he likes.

End quote from Liqa’ al-Baab al-Maftooh (49/6)

This is the guideline with regard to what is required of the
child in terms of obedience to his parents.

Based on that:

If your staying up at night is detrimental to your parents’
interests, because it will lead to you sleeping for a long time during the
day, which will prevent you from doing what they ask of you, then in that
case it is obligatory for you to obey them.

But if you can take care of their interests and serve them,
and not fall short in that, then what appears to be the case is that you are
not obliged to obey them with regard to not staying up at night.

If you are not able to get up to pray Fajr except by staying
up all night in the summer, then there is no blame on you if you stay up at
night for something that is of benefit to you, and thus be able to pray Fajr
on time.

In this case you should try to win your parents’ approval,
and explain to them that you are only doing that because you are keen to
pray Fajr on time.

Whatever the case, what you must do is strive to offer the
prayer on time, for prayer is the best and noblest of deeds, and one of the
greatest of prayers is Fajr prayer.

But you should try to look for other alternatives so that you
do not have to stay up all night, such as using an alarm clock or phone, or
asking one of your friends to call you to wake you up, or perhaps your
parents can help you and wake you up, and other solutions which will combine
the interests of praying on time and pleasing your parents with other
interests that will benefit you, namely sleeping at night, which is more
beneficial and healthy than sleeping during the day, because staying up at
night has an impact on a person’s health and energy in general terms.

And Allah knows best.
