Holidays Are Part of the Complete Deen

After the above lengthy discussion which, as stated earlier, is meant
toprovide general guidelines concerning celebrations and other related
matters, we comeback to apply what we have learnt so far to the
subject at hand.
Prophet Muhammad (S) once saw the Ansaar celebrating a certain day.He
inquired about that and was informed: This isone of two days that we
used to celebrate in Jaahiliyyah (pre-Islaamic ignorance) and we
continue to do so. He replied: Nay! Allaah has substituted for you two
better days: the day of al-Fitr and the day of al-Adhhaa. [Authentic;
narrated by Ahmad, an-Nasaaee, and others]
In addition to these two days, the Jumu ah (Friday) is an eid day.
TheProphet (S) said: This is a day which Allaah has designated as an
eid for Muslims. [Authentic] Fromthis and the previous hadeeth, we
conclude that Muslims have only three eid days, a weekly eid every
Friday, and twoannual eids, al-Fitr and al-Adhhaa.
Also, Islaam instructs us as to how to celebrate our eids. No fasting
is allowed on these days (Friday is excepted undercertain conditions).
On eid days, Muslims take a bath and wear their best clothes. They
avoid all forms of sinning which people tend to commit when they are
in a state of rejoice. The major partof the celebration is not eating
or drinking. Rather, it is a prayer which gathers Muslims together to
remember Allaah's bounties and to chant His glory and greatness.
It becomes clear then that Allaah alone has the right:
1. to prescribe eids and toset their dates, and
2. to prescribe the manner of celebrating them.
