He does not neglect of the correct martial arrangement and selecting the best methods of army even for a moment, and, in the meantime, by applying different ways, he strives to create a gap between the rows of the enemy. Yes, he is the best leader and excellent pattern of conduct for the believers in this field and in all fields.
It is interesting that the Qur’an in the above verse considers this excellent pattern specific to those who have these three specialties: being hopeful in Allah, hopeful in the Day of the Hereafter, and remembering Allah very much.
In fact, faith in origin and Resurrection is the motive of this motion, and the remembrance of Allah is the cause of its continuation; for, no doubt, the one whose heart is not filled with such a faith, is not able to act like the manner of the holy Prophet (S), and also, in the continuation of paving this way, if he does not ceaselessly remember Allah and does not send away Satans from himself, he will not be able to continue the proper imitation.
“And when the believers saw the allies, they said: ‘This is what Allah and His Messenger promised us, and Allah and His Messenger spoke the truth; and it increased not in them but faith and submission.” Formerly, in verse 12, we recited that the hypocrites and those in whose heart was a disease counted the promises of the Messenger of Allah a delusion, while, in this noble verse, the believers consider them the truth.
In this holy verse, the Qur’an refers to the state of the true believers and says: “And when the believers saw the allies, they said: ‘This is what Allah and His Messenger promised us, and Allah and His Messenger spoke the truth; and it increased not in them but faith and submission.” Which promise was it that Allah (s.w.t.) and His Messenger (S) had promised?
