Islam prescribes a maximum of three days of mourning for the death of a family member. Once the three days are over, one should resume normal life as best as possible – including taking part in celebrations. The Prophet (peace be upon him) said, “It is not permissible for a person who believes in Allah and the Last Day to practice mourning for more than three days – except in the case of a wife observing the period of waiting following her husband’s death.”
There is no doubt that renewal of grief and mourning in such a way as to interfere with the spirit of celebration is undoubtedly undesirable, and must be avoided. Having said this, if someone wants to visit the graves of parents or deceased relatives while observing celebrations, there is no harm in doing so.
Almighty Allah knows best.
