We have already sent Our messengers with clear evidences and sent down (57:25)

Almuntakhab Fi Tafsir Alquran Alkarim

We have previously and thus early sent Our Messengers with expounded revelations and elucidated signs and accorded them Books and authority to administer wisdom and induce the war of justice against injustice, so that people learn the conformity to the truth and the justness of perception to deal with facts and deny falsehood. And We provided the earth with iron to attain a purpose, as will as power and strength in war against tyranny and falsehood and to be of service in effecting ones object to do what is needed in life. Allah shall know who among the men do intend to direct their minds and their thoughts to striving in His cause and to the support of His Messenger to attain Allahs purpose; Allah is indeed Qawiyun (Omnipotent) and Azizun

*45) In this brief sentence the whole essence of the mission of the Prophets bas been compressed, which one should clearly understand. It says that all the Messengers who came to the world from AIIah, brought three things:
(1) Bauuomatat: manifest signs which clearly showed that they were really Allah's Messengers, and were not impostors; convincing arguments which made it evident that what they tore presenting as Truth was really the Truth, and what they condemned as falsehood was really falsehood clear instructions which told without any ambiguity what was the. right way for the people in respect of beliefs, morals, acts of worship and dealings, which they should adopt, and what were the wrong ways which they should shun and avoid.
(2) Kitab: the Book which contained all the teachings required for the guidance of man so that people may turn w it for enlightenment.
(3) Mizan: the Criterion of truth and falsehood which may precisely indicate, like a balance, the golden mean between t40 extremes in matters of thought, morals and dealings.
The object for which the Prophets were sent with these three things was that man's conduct in the world and the system of human life, individually as well as collectively, should be established with justice. On the in hand, every man should precisely know the rights of God, the rights of his self and the rights of all . these people with whom ne may have w deal in any way, and should fulfil them faithfully; and, on the other, the system of collective life should be built on such principles as should eliminate every kind of injustice from society, should safeguard every aspect of civilization and locial life against extremism, should establish correct balance and equity in all spheres of collective life, so that all elements of society should receive their rights equitably and fulfil their obligations and duties responsibly. In other words, the object of sending the prophets was to establish individual as well as collective justice They wanted to establish justice in the personal lift of each individual so as w bring about poise and equilibrium in his mind, his character, his conduct and his dealings. They also wanted to establish the whole system of human society on justice so that both the individual and the society should assist and cooperate with each other in their spiritual, moral and material well-being instead of being a hindrance and obstacle.
*46) Sending down iron means creating iron in the earth just as in Az-Zumar:6 it has been said: "He Scat down for you eight heads of cattle, male and female." As whatever exists in the earth, has come hero by Allah's command, and has not appeared by itself, its being created has been expressed in the Qur'an as its being sent down. The mention of "sending down iron which has greath strength and other benefits for men" immediately after stating the object of the mission of the Prophets by itself indicates that by iron here is meant political and military power. Thus the verse means: "Allah did not raise His Prophets in the world just to present a scheme for the establishment of justice, but it was also a part of their mission w endeavour to enforce it practically, w collect necessary power to establish justice in all spheres of life, w punish those who might disrupt it and to break the power of those who might resist it. "
*47) That is, "Allah does not need this help because He is weak and cannot use His power to accomplish this work, but He has adopted this method for the trial of men: man can advance on the way of his progress and well-being only by passing through this trial. Allah indeed has the power w subdue all the disbelievers by one command whenever He wills and give to His Messengers complete dominance over them, but in that case the believers in the Messcngers would have - nothing to do for which they should become entitled to rewards. That is why Allah instead of accomplishing this mission through His dominant power adopted the method of sending His Messengers to human beings with the Signs and the Book and the Criterion, and enjoined them to present the way of justice before the people and exhort them to refrain and desist from wickedness sad injustice At the same time He gave us full option to accept the message of the Messengers or to reject it. He summoned those who accepted the invitation to come forward and help Him and His Messengers to establish justice, and to exert their utmost against those the were bent upon retaining the unjust system. Thus, Allah wants to see who among us reject: the invitation to justice, who exert with their lives in order to retain injustice as against justice, who shirk: supporting d struggling for the cause of the message of justice after they have accepted it, and who stake their lives and their possessions for the sake of unseen God to help the truth become dominant in the world. Only for those who emerge successful in this test will avenues to fixture progress be opened up. "
