The above mentioned verse also alludes to an important fact, that, fighting may be inevitable, but it should not always be so glorified that could result to the exclusion of other important things, like learning and education. This is because in the sight of God the ink of the learned and the scholar is dearer than the blood of the martyrs! Muslims warriors had better to divide in two groups. One party had to go forth in the field, to fight the enemy when the prophet himself was not leading the army and remained in the capital. And the next party had to stay with the prophet to learn theology, in order to teach the other fighters when they returned from the battle- field. Of course in this case both the learners, and the teachers, were soldiers and warriors!

      Learning wisdom and knowledge is also some sort of fighting against the devil of ignorance, and is no less important in the sight of Allah, than fighting against heathenism.

      Therefore some of the believers were ordered to remain in Medina with the Messenger of God, for the purpose of study and learning, so that they could teach the warriors later on.

      The verse under discussion also implies that a group of muslims, always have to go for learning in the centers of education and knowledge, and in the place where wisdom and theology is being taught, in order to learn something and come back to teach their citizens. This order will remind us of the famous tradition related from our prophet who said:ِ

      ``Seek knowledge even if you find it in China.''

      On the other hand, this verse clearly implies how important learning and teaching is in the sight of God and in Islam. Here a group of Muslims are ordered to leave JAHÄD, which is one of the most important commandments and attend the classes for learning and then teaching what is learnt. This is why Muslims are the pioneers and pillars of science and knowledge in the world.

      One of the expounders of the holy Qurän has a remarkable comment here in this verse- he says:ِ

      ``I was in TRIPOLIS for study, when the governor there who had a good knowledge of Islam, said to me: why does Persian government exempt the theological Students of Qom, from military services, while this sacred service is more becoming to them, and befits them?

      The commentator, Remembered the above verse and told the governor:ِ

      The believers should not go forth all together. Rather a body of each division of them should stay behind with the prophet in Medina to learn theology and learn the knowledge of religion and belief in order to preach and teach the others.

      As a matter of fact, in any field of knowledge and branch of science, some students must study deep to become expert in order to satisfy the needs of their community; and the knowledge of religion and belief is not an exception among the fields of knowledge.''
