The Ruqyah application for fussy babies with difficulty sleeping is useful for mothers and fathers.
Children are innocent creatures and are still very vulnerable to jinn interference. Therefore, as parents, we must be alert from the attacks of spirits on our children, because we are charged with the responsibility to protect them. There are indications that children are disturbed by jinn, including:
1. Feeling someone is following or whispering
2. Like to be dumb or talk to yourself
3. Growing abnormally (ex. : Talking for a long time, walking for a long time, etc.)
4. Frequent nightmares
5. Likes to fuss

Ruqyah is a method of syar'i treatment that was exemplified by the Prophet to ask for protection from calamities and diseases. It is done by listening to the reading of the verses of the Qur'an.
In this application you can play melodious ruqyah verses.
