People make sure that the food that is prepared and put on the table when doing khathams, is eaten and also finished and not wasted. They think it’s blessed becasue it is khatham food and also it will be a sin if the khatham food is wasted etc. So the khatham food is treated with a lot of respect and love.
Is it kufr by having the above thinking and believing about khatham food?
When does this happen?
Why does this happen?
To willfully call people to ‘Katham Quraan’ functions is not proven in Islaam.
To feed people thereafter is also not proven.
The one attending such functions and eating thereof does not become a Kaafir.
