Does not wearing hijab invalidate the fast?

I am a girl who does not wear hijab. Does that mean that my fasting in
Ramadaan is invalid?.
Praise be to Allaah.
The believing woman is enjoined to wear hijab. We have discussed hijab
on this site in the answer to more than one question, and these
answers tackle the matterfrom different angles. Some of them focus on
the ruling on hijab and point out that it is obligatory, as in the
answer to question no. 21536 . Some quote the definitive evidence for
hijab being obligatory, such as the answer to question no. 13998 and
11774 . Some describe theshar'i hijab, such as the answer to question
no. 6991 . Other answers speak of the importance of hijab in the life
of the believing woman.
Secondly:
If a woman does not wearhijab, then she is disobeying her Lord
thereby, but her fast is still valid, because sins, including not
wearing hijab, do not invalidate the fast, but they detract from its
reward, and may cause it to be lost altogether.
What we urge you to do is wear hijab as well as fast, because the aim
of fasting is not merely to give up food and drink, rather the aim is
to fast orabstain from haraam things. Hence the Prophet (peace and
blessings of Allaah be upon him) said: "Fasting is not just
(abstention) from food and drink, rather fasting is(abstention) from
idle andobscene talk." Narrated byal-Haakim and classed as saheeh by
al-Albaani in Saheeh al-Jaami' (5376).
Idle speech refers to that in which there is no benefit.
So let your fasting motivate you to obey Allaah and keep away from
that which He has forbidden.
We ask Allaah to help youto do that which He loves and which pleases Him.
And Allaah knows best.

by hitting or shouting at students?

I work as a teacher and sometimes I have to hit orshout at the
students, because all the teachers do that. I have tried to make
myself not do that, but it happened today. Is the fast invalidated by
hitting and shouting and getting angry? Do you advise me to give up
this profession because of what it leads to of lack of psychological
instability, and it is affecting my worship of Allah because Ifeel
guilty after hitting or shouting? Please note that I would do that
wereit not for my mother who may be upset if I give it up.
Praise be to Allaah.
Firstly:
Hitting and shouting are not things that break the fast, even if it is
done by way of aggression, so how about if the hitting and shouting
are done forthe purpose of discipline, teaching and directing?
Undoubtedly in that case it is clear that they do not break the fast.
Please see the answer to question number 106473 .
Secondly:
We advise you to remain in this job -- teaching -- because it is one
of the noblest and most important kinds of work, and it is essential
to pay attention to knowledge and teaching, and to make sacrifices for
the sake of reviving our schools and universities and taking them to
the highest levels and most sublime of goals. Try to overcome every
problem you face in your work with wisdom and deliberation, and
consult former teachers who haveexperience.
We ask Allah to guide andhelp us and you in this world and to grant us
success in the Hereafter.
And Allah knows best.

Vaccinations against meningitis do not invalidate the fast

Does a vaccination againstmeningitis invalidate the fast?.
Vaccinations against meningitis do not invalidate the fast. There is
nothing wrong with that, but if it is possible togive the injection at
night,that is more on the safe side. And Allaah is the Source of
strength. May Allaah send blessings and peace upon our Prophet
Muhammad and upon his family and companions.

Where to pay zakaat al-fitr

I am a young man living in Kuwait, but I have taken my daughter to
America for medical treatment and I fasted Ramadaan in America. Do I
have to pay zakaat al-fitrin America or can I delegate my family in
Kuwait to pay it on my behalf? What is the ruling on paying zakaat
al-fitr in cash? Please note that in America they pay it in cash
instead of giving staple food.
Praise be to Allaah.
The scholars (may Allaah be pleased with them) stated that zakaat
al-fitr isconnected to numbers of people, not money, and it is to be
paid in the place where a person is on the night before Eid.
Ibn Qudaamah said in al-Mughni (4/134):
As for zakaat al-fitr, it is tobe paid in the land where the person
from whom it is due is present, whether his wealth is there or not.
End quote.
As for paying zakaat al-fitrin cash, we have explained in the answer
to question no. 22888 that it must be given in the form of food, and
thatpaying it in cash is not acceptable.
So you must try to give it in the form of food. If the poor person
refuses the food and asks for cash, then there is nothing wrong with
your giving it as cash in that case, because of need or necessity.
And Allaah knows best.
