In the first stage...
In the first stage, it is essential for the head of the household, who is responsible for managing life's affairs to have enough knowledge of religion as required by his personal duty and, as much as is necessary of religious jurisprudence knowledge: this means to be informed of the religiously lawful and forbidden actions and things. He must have as much as necessary of worldly knowledge in order to run life.
In the next stage and under the support of the man of the house who provides the necessities of the family, the wife and the children can live as a small nation in the small country of the home. They can live together with knowledge, wisdom, insight and awareness, and be secure from the evils of ignorance, illiteracy, jealousy and foolishness. Verily knowledge provides security and ignorance and illiteracy will result in loss.
Ignorance and Illiteracy In a very important statement made by members of the Prophet's family, ignorance is considered to be a kind of spiritual death and to be more detrimental to one's life than a harmful meal. Ignorance is an illness, some sort of suffering, a source of deviation bringing on ever-lasting misfortune. It ruins one's future life, is a mine of evil and a dangerous enemy. Ignorance is the cause of unbelief and deviation, and prevents sermons and advice from being accepted.
It also is the cause of excesses in life. The Commander of the Faithful, Imam Ali (Pbuh) said: Ignorance is death; ignorance is destruction; ignorance is an incurable disease; ignorance is a cause of man's slippage; ignorance ruins the Hereafter; ignorance is the source of all evils; and ignorance is the main stock of evil. [Mizan al-Hikmat , v.2, p.154] The Prophet (Pbuh) was asked about the signs of the ignorant. He answered as follows: An ignorant will trouble you if you socialize with him.
He will blame you if you stay away from him; he will mention it if he grants you something; he will be ungrateful if you grants him something; and if you trust him with your secrets, he will misuse your trust. [Tuhaf ul-Uqool , p.28] Consider the following matter for yourself.
If the head of the household is ignorant, does not consider spiritual and doctrinal matters to be important and has no worldly plans in mind, then he will be a great source of stress, insecurity, trouble, suffering and torment in and outside of the home.
