At the end of the day, it's not a 'book' or 'logic' which will make anyone pray . . . It is a longing for Allah, a love of him and his messenger sallaLlahu 'alayhi wa alihi wa sallam, fear of displeasing Him, and a subsequent desire to obey his commands which will drive one to pray Salah. This is the tarbiyah that needs to be instilled in children. was-salam
