6- Make Dua!
We can teach our children all we know about the Quran, we can make efforts to raise them as practicing Muslims, we can remind them about Allah and the Quran; but in the end we do not control their hearts. Neither can we be with them, supervise them or correct them 24/7.
However, we can make Dua to the one who does in fact control their hearts and is with them 24/7. We must never underestimate the power of Dua. The day I increase the quality and quantity of my supplications I start seeing the effects in myself and my child. Remember, ultimately the most important thing is YOUR connection with Allah. Pray to Allah to develop the love of His book in your children.
May Allah engrave the love of Quran in us and our children and make it the spring of our hearts. Ameen!
