All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
There is no doubt that having a television at home for children to watch and become attached to is wrong. It is no wonder that children do not memorize the Quran by heart because television occupies them.
You should do the following:
1- Ask an expert in reciting the Quran to teach this child to memorize the Quran by heart and to pronounce it correctly.
2- Read the chapter of Al-Baqarah every three days in your house. You may also play a tape recording of this chapter.
3- Teach children to mention the name of Allaah The Almighty before eating, drinking and entering the house and the bathroom.
4- Ask the father or any other person to make Ruqyah (Quranic treatment) for the children. He should read the chapters of Al-Falaq, An-Naas and Al-Ikhlaas and the verse of Al-Kursi [2:255] before them. Alternatively, you may read them before a container of water then pour this water over them. This should be done from time to time.
You should also remove anything that would hinder angels from entering the house, e.g. dogs, statues and pictures depicting humans, animals or birds. Moreover, you should ask a devout Muslim to read the Quran before the child.
Allaah Knows best.
