Are parents responsible if a child decides to leave Islam ? If parents did teach Islam, rules, to the child during childhood.
Salaam. A parent can only teach their children, but cannot force a child to believe in something. Islamic law prohibits forced conversion, following the Quranic principle that there is "no compulsion in religion" (Quran 2:256). Thus, the best thing you can do is pray to Allah (swt) to guide your child and also try to give resources to your child. I hope this helps:)
