As Salaamu Alaikum,
I have an atheist son age 4_, who was once a good Muslim (in early teens) he seems to believe that his ideas are ok to discuss with our grand children, other Muslim family members and on occasions even argue with me about my beliefs.
I have tried so many years to be patient with him, he has an alcohol issue and have put much of this on that. However lately I have been more annoyed at his efforts to indoctrinate my younger grandchildren, siteing his “scholars” like Darwin and others to bolster his position.
No matter what we do as a family to get him to at least stop promoting his un-Islamic ideas, he argues why his views have to be silenced? I respectfully request your opinion on how to handle this situation, with Ramadan coming I know this will be a problem, yet again.
Tell him he is welcome to promote his views under his own roof without hindrance, but in your house he needs to respect your rules. As for the grandchildren make dua for them especially this Ramadan, feed them halal food when they are with you, and through your own good example your teachings will also be part of their inheritance and will balance materialistic constructs.
