Praise be to Allaah.
Celebrating the Mawlid (Prophet’s birthday) is bid’ah (an
innovation). It is not narrated from the Prophet (peace and blessings
of Allaah be upon him) or any of his companions or the Taabi’een or the
Imams. Rather it was innovated by the ‘Ubaydis (Fatimids), who also
introduced other innovations and misguidance.
The fact that this celebration is an innovation has been
discussed in the answer to question no. 10070 and
The basic principle is that it is permissible to eat and
drink sweets that are free of harmful ingredients, so long as that is not
helping in evil or propagating or encouraging its survival.
It seems that buying Mawlid sweets at the time of that
celebration comes under the heading of helping and propagating it; rather it
is a kind of establishing that festival or eid, because an eid is something
that people observe regularly. If it is their custom to eat this specific
food or they make it for that festival, unlike their habits at other times
of the year, then buying and selling it, and eating it or giving it as a
gift, on that day, is part of celebrating that festival or establishing it.
So it is better for you not to do that on the day of the celebration.
In Fataawa al-Lajnah al-Daa’imah there is a discussion
to do with Valentine’s Day and buying sweets that have been coloured red and
on which hearts are drawn, as an expression of celebrating that innovated
festival. It says:
The clear evidence from the Qur’aan and Sunnah – on which
there is consensus among the early generations of the ummah – that there are
only two Eids or festivals in Islam: Eid al-Fitr and Eid al-Adha. Any
festivals other than these, whether they are connected to a person, a group,
an incident or anything lese, are innovated festivals and it is not
permissible for the Muslims to celebrate them or approve of them, express
joy on them or help with them in any way, because that is transgressing the
sacred limits of Allaah, and whoever transgresses the sacred limits of
Allaah has wronged himself. … It is also haraam for a Muslim to help with
this festival or any other haraam festivals in any way, whether it has to do
with food, drink, selling, buying, manufacturing, giving, corresponding,
announcing or anything else, because all of that is cooperating in sin and
transgression and disobedience to Allaah and to the Messenger of Allaah,
(peace and blessings of Allaah be upon him), and Allaah says
(interpretation of the meaning):
“Help you one another in Al‑Birr and At‑Taqwa (virtue,
righteousness and piety); but do not help one another in sin and
transgression. And fear Allaah. Verily, Allaah is Severe in punishment”
And Allaah knows best.
