I want to know a quranic amaal, for both of my boys, ages 3 and 5.
Both of them have severe behavioral issues. The older one has autism and is five years, but doesn’t speak anything and doesn’t understand complex language also.
The younger one is 3 years, has sensory processing disorder, and has severe severe tantrums to the point of hysteria and it becomes extremely difficult for me to control them.
Please tell me some quranic amaal or some surah which I can write and put it as taweez around their necks.

I'm sure you must be doing a lot of aamal and duas. I request you to kindly pay full attention to physician's recomendations as dua and medication go together.
