In the Name of God, the Compassionate, the Merciful
Purification prior to knowledge
The fact that you said the students whom join the warfronts and study as well are appreciable. I pray for all of them. All should be engaged in the war. However, the important question is to treat education and purification together. Education alone is of no avail. It is sometimes harmful. The amount of damage Iran has suffered by Westernized thinkers and modernists has not sustained by any others. It was because they had received education without purification. The basis that was edification had not been cared for. They trained our children from kindergarten to university in a way as to be harmful to the nation and the country and useful for others.
You should note that the school period is important than university, because mental growth of children takes shape in this period. We should try hard so that those who raise our children with corrupt mentality would not enter schools and universities. This should not be neglected. They might not do anything at the moment, but they will do their job ten years later. We are opposed to those who are hostile to Islam and stand against them, but we do not bother those who are not hostile to Islam and concerned with their own business. Our concern is Islam and Muslim country. We have offered so many youths for Islam, so we should not let their blood to be wasted. What do we want for the scientist who is harmful to humanity? Today, the world is burning in the fire of the knowledge of pernicious scientists. These destructive weapons, bombs and missiles have been made by these very scientists. Therefore, knowledge should be combined with purification. Basically, purification of the self is prior to knowledge.
Heavy responsibility of teachers in educating students
All teachers should think of purifying themselves so that their words impress others. Teachers should know that their job is very crucial; they should be careful to raise children in good conditions from the very beginning that the university will be late. Teachers should feel that they are responsible before God. If children are trained in bad environment, the teachers are accountable. If in this case you and I keep silent, we are also responsible.
I hope that people make the necessary effort for construction of schools which are for their own children. Assistance of schools is assistance to their children, this country and the nation. We should flourish the country. I hope that people would offer assistance as much as they can; they should not think that the figure they assist should be big. One can participate in construction of schools with small figures. Of course, big figures have their own place. Give my regards to teachers and students. Tell them in classes that they should train themselves for future.
May God's peace and mercy be upon you!
