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 matter from
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 the shar’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 wear
hijab, 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 or abstain 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 and obscene talk.” Narrated by al-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 you
to do that which He loves and which pleases Him.
And Allaah knows best.
