السلام عليكم ورحمة الله وبركاته احسن الله إليك If my elder family member is saying something about islam, like jinn travel through radio waves, and it is in front of my family, must I say something there in them if i know that it won’t be taken well and other people aren’t taking it seriously?

Ustadh AbdulAziz al-Haqqan

Don't say anything. Barakallahu feekum.
