A child’s education is influenced at a large extent by how much parents act upon what they believed in align what is expected from the child. If you want your child to be fearing of Allah, then he needs to be in relationship with someone who fears Allah. Right now it’s the opposite as he is surrounded by those who want others to be fearful.
The child is confused that the person who wants me to be fearful of Allah SWT is not afraid of Allah himself. This is a big concern of the child. If a child comes in relationship with someone whose eyes get tearful with the remembrance of Allah SWT, that child will automatically develop strong belief in Allah SWT, no curriculum will be needed.
If you yourself come in relationship with someone whose voice shivers while thinking of akhirah; who sheds tears out of fear and remembrance of Allah SWT, everything will be straighten up by itself just by being in relationship with him.
A child is already getting educated in the best madrassa whose mother is fearing of Allah SWT. Similarly, the child is already getting educated in the best school whose father is fearing of Allah SWT and is also the favorite person of his child. If father of a child has his eyes wet out of fear of Allah SWT and he is the favorite person of his child (if these two conditions are fulfilled), the child is already enrolled in the best religious education program. Their relationship is already doing that. In fact, education is nothing but relationship with mentor and school is where the mentor is. Our society has failed to realize that.
The importance of being a mentor and developing relationship with the child, is not realized nowadays. If you are very religious but you don’t have a good relationship with your child then you will be the one who will keep him away from being religious. You like religion very much but are not the favorite person of your child, then you will not make it any easier for your child to come close to religion.
