It is a tough responsibility but with great rewards for the children and their parents. The proper upbringing that we may provide our children today will be a good investment for the future, especially after death. This Islamic upbringing is a duty we owe to our children as Muslim parents. It is a noble duty that cannot not be left or assigned to others. It is the joint responsibility of the parents who will be asked about it, at the day of Judgment.
Some parents fail to take their responsibility seriously.
They are either too busy earning a living, making money, or are unaware of this responsibility at all, either because of ignorance or indifference. When things start going wrong and they see their children go astray, they may wake up and they may realize the need for action to protect their children and save them from falling in evil and Haram and following the wrong path. Some people think that because children are children, they will always be children. Some parents think that because they are Muslims, their children will be Muslims. This is not true always.
