There is nothing you can do more! Their guidance is in Allah’s hands. Prophet Nooh’s son died a kafir!

Keep on trying to call them back gently and make a lot of Duaa.

Respected sheikh,_I’m very worried. My children (son and a daughter) are going away from deen. Although both my husband and I are practicing muslims alhumdulillah. We have always tried to pass on the religious values to our children and also made arrangements for their religious education but it is painful to see both the children going far away from deen.
