Birthdays are not allowed in Islam, likewise I would like to know is it allowed to celebrate death days.
This question may seem little bit strange though, as by celebrate I means, calling people on that particular day giving food to all of those who are present there, even a young imam (it means a young guy studying under an imam) or imam will be present there for praying for the dead.
Honestly the gathering over these kind of places I hardly or you can say 99% of them may not grieve for the dead, and on the other side all are laughing, having food something like a mini wedding party.
Also I find on the 3rd day after death a similar kind of party you can find among few Muslims, then after 14 or 17th day followed after 40 days and to yearly basis.
Is there any Islamic backing for the above mentioned action?
