The following hadith narrated by `Abdullah ibn Fazl from the fifth or sixth Imam is very significant to understand what is meant by gradually: “When the child reaches 3 years of age, teach him seven times to recite la ilaha il-lal lāh. Then leave him at that till he is 3 years, 7 months and 20 days old; then train him to say Muhammadun rasu-lul lāh. Then leave him at that till he completes 4 years, then teach him seven times to say sal-lal lāhu `ala Muhammadin wa āli Muhammad .
Then leave him at that till he reaches the age of 5 years; then see if he can distinguish between the right and the left hand. When he knows the difference, then make him face qiblah and tell him to do sajdah . This is to continue till he is 6 years of age. Then he should be told to pray and taught ruku` and sajdah . When he completes 7 years, then he should be asked to wash his face and hands, and then told to pray.
This will continue till he reaches the age of 9 years, when he should be taught proper ritual ablution for prayer and proper salāt. When he learns proper wudu and salāt, Allah forgives the sins of his parents.” The Second Stage: from age eight to fourteen.
The Prophet said, “The child is...a slave for [the next] seven years.” Since this is the age when the child's mind can grasp logical reasoning and is developed for formal education—it is very important that the child not only be educated but, at the same time, he or she should be raised with proper Islamic ethics. By saying that the child is a “slave” from eight to fourteen, the Prophet wants to emphasize that at this age the parents should be strict in disciplining their children.
A child is a “slave” in the sense that he has to follow the instructions of parents and teachers. In the sayings of the Prophet (s.a.w.) and the Imams of Ahlu 'l-byat (a.s.), three things have been emphasized for the male children in the second stage of upbringing: 1. literacy for secular knowledge; 2. religious knowledge and 3. physical education and martial arts.
For example, the Prophet (s.a.w.) said, “It is the right of the male child on his father to...teach him the Book of Allah...and riding and swimming.” Imam Ja`far as-Sadiq (a.s.) said, “It is the duty of the father to teach his son writing.” Religious education is very crucial at this stage so that the child's religious beliefs are based on sound reasoning and firm foundation.
