Having a Quraan khatam once a year for the deceased
Q: My in laws have a culture of performing Quraan khatam once a year for the deceased by having someone or a group reading Quraan and send esaale sawaab to the deceased father or Muslim family members. There is also intermingling of opposite sexes at the event. Cooking etc. and feeding the guests.
My question is, are all those efforts counted in the court of Allah, such as Quran tilwawat, dua for the deceased etc., whilst there is no pardah between the opposite sexes, intermingling etc. at those gatherings?
