The family is the most important informal institution in the formation of children’s morals with Islamic religious education. The position of the child as a mandate from God then formed a three-dimensional relationship with parents as the center. The relationship of children who still need guidance with God through parents and the relationship of children with parents under God’s guidance. But on the other hand, the family can also be a killing field for the development of a child’s soul if the parents wrongly educate them. The existence of this post truth in the era of the industrial revolution 4.0 makes parents control a lot of children’s activities, especially in the use of social media. Because the family is the only educational institution that is able to carry out the way of religious education through good example and habituation from parents to their children.
