Shaykh Abdul-Muhsin al-Abbaad was asked:
I was granted a child. Is it permissible for me to share the news on internet websites or on Facebook so Dua can be made for him?!
No never don’t do that, (rather) you (should) make Dua for him, and (also) his family should make dua for him and do not busy yourself with these affairs. Everyone who is granted a child, runs and puts it up on the internet?
