Respected brother/sister

It is true that the Hadeeth states to the effect that when a person dies, and those left behind cry loudly over his/her demise, then the deceased is punished.

Ulamaa have written that the deceased is punished only if they had instructed their family to cry upon their death. This may seem odd at present, but in the days of ignorance, people used to make an event out of mourning. There used to be people in the community whose profession was to go and cry loudly at funerals, just as you would have people who would go and sing at weddings. Islam put an end to this baseless custom and prohibitted Muslims from crying loudly as it portrays impatience and displeasure upon Allaah's will.

And Allah knows best

Wassalaam
