أحسن الله إليكم Shiekh, I use ma'areed to not let anyone know I'm fasting voluntarily. Like if my stepmom asks me if I ate and I say I ate earlier meaning suhoor and will eat later meaning iftar, is this permissible?

Ustadh AbdulAziz al-Haqqan

But why? is there any harm in saying that you are fasting?
