IMPORTANCE OF ISLAMIC SCHOOL OR EDUCATION
Read and your Lord is Most Honorable, who taught (to write) with the pen taught man what he knew not Those of His servants only who are possessed of knowledge fear Allah; surely Allah is mighty of forgiving. (28/35
Prophet PBUH said: Seeking knowledge is obligatory to every Muslim Men and Women
He also said: I am the City of Knowledge and Ali is the Door of the City
The reason that the Quran has urged us to reflect upon Creation and to study the natural world and acquire knowledge is to confirm in us mankind’s instinctual freedom of thought upon which all sages are in agreement, in order that the power of human understanding and thinking may be so enlightened that it may fulfill the function of which it was Created.
 Children are invaluable assets of future generations. Islam has given particular attention for their education and training as well as for their respect, love, and affection. Islam provides detailed instructions for preservation of children’s rights and emphasize for their guidance so that they could endeavor for perfection as human beings with an aim of worshipping Allah and serving the humanity.
 The best inheritance that we provide to our children in this life is Islamic Education. We always worry about standard of education in public school, but why not about Islamic Education. Sending children to Sunday School is not a formality. We do not realize that two hours a week are not enough for Islamic Education. Sunday School tries to instill in our children the teaching of Quran, History, and Fiqha, but it cannot succeed until the parents follow up the work everyday. Children should practice Quran everyday.
 Sunday School is not Howza (Islamic University). We are not here to create a Mujthid. But to teach our children the best way to be on the path of Islam, like Wajeb, Haram, Halal, Makroh, and the Communication of Allah from Quran. To achieve these five goals the best in life, they have to learn these before college starts. As they take up more responsibilities, they tend to make up excuses.
Remember Islam is not a tradition. This is the code humans need to follow during their entire live. Islam is all about Justice and the avoidance of indecency and evil.  Muslims living in western countries has to pay more attention to the Islamic education of their children, with out looking   there personal differences, or family problems.
And if they fail in this duty, their children will say : my parents and grandparents were Muslims but I am an atheist.
If Person learn knowledge,  then he fear Allah and he follow his command only, then he should not depend or rely on any one but Allah.  Allah is Mola and Wakeel, He know in side of our hearts that's the teaching of Quran for especially Ulama.
Those who deliver the massages of Allah and fear him.  and do not fear any one but Allah. and Allah is sufficient to take account 33/39 Quran
