COMMENTARY on 57:25
A. Yusuf Ali:

Translation:
We sent aforetime our messengers with Clear Signs and sent down with them the Book and the Balance 5313 (of Right and Wrong), that men may stand forth in justice; and We sent down 5314 Iron, 5315 in which is (material for) mighty war, as well as many benefits for mankind, that Allah may test who it is that will help, Unseen, 5316 Him and His messengers: 5317 For Allah is Full of Strength, Exalted in Might 5318 (and able to enforce His Will).
Commentary:

5313  Three things are mentioned as gifts of Allah. In concrete terms they are the Book, the Balance, and Iron, which stand as emblems of three things which hold society together, viz., Revelation, which commands Good and forbids Evil; Justice, which gives to each person his due; and the strong arm of the Law, which maintains sanctions for evildoers. For Balance, see also 42:17, and n. 4550.

5314  Sent down: anzala; in the sense of revealed to man the use of certain things, created in him the capacity of understanding and using them: Cf 39:6: "sent down for you eight head of cattle in pairs".

5315  Iron: the most useful metal known to man. Out of it is made steel, and from steel and iron are made implements of war, such as swords, spears, guns, etc., as well as instruments of peace, such as ploughshares, bricklayers' trowels, architects' and engineers' instruments, etc. Iron stands as the emblem of Strength, Power, Discipline, Law's sanctions, etc. Iron and steel industries have also been the foundation of the prosperity and power of modern manufacturing nations. (R).

5316  In 21:49, I have translated "in their most secret thoughts" for the more literal "unseen" (bi al ghayb). Perhaps the more literal "unseen" may do if understood in the adverbial sense as explained in 35:18,— n. 3902. The sincere man will help the Cause, whether he is seen or brought under notice or not.

5317  To help Allah and His messengers is to help their Cause. It is to give men an opportunity of striving and fighting for His Cause and proving their true mettle, for thus is their spirit tested. As explained in the next line, Allah in Himself is Full of Strength, Exalted in Power, and Able to enforce His Will, and He has no need of others' assistance.

5318  Cf. 22:40 and n. 2818. "Strength" is specific; Power or Might is more abstract, the ability to enforce what is willed.

 

Muhammad Asad:

Translation:
Indeed, [even aforetime] did We send forth Our apostles with all evidence of [this] truth; and through them 41 We bestowed revelation from on high, and [thus gave you] a balance [wherewith to weigh right and wrong], so that men might behave with equity; and We bestowed [upon you] from on high [the ability to make use of] iron, in which there is awesome power as well as [a source of] benefits for man: 42 and [all this was given to you] so that God might mark out those who would stand up for him and His Apostle, 43 even though He [Himself] is beyond the reach of human perception. 44 Verily, God is powerful, almighty!
Commentary:
41  Lit., "with them".
42  Side by side with enabling man to discriminate between right and wrong (which is the innermost purpose of all divine revelation), God has endowed him with the ability to convert to his use the natural resources of his earthly environment. An outstanding symbol of this ability is man’s skill, unique among all animated beings, in making tools; and the primary material for all tool-making - and, indeed, for all human technology - is iron: the one metal which is found abundantly on earth, and which can be utilized for beneficial as well as destructive ends. The awesome power (bas shadid) inherent in iron manifests itself not merely in the manufacture of weapons of war but also, more subtly, in man’s ever-growing tendency to foster the development of an increasingly complicated technology which places the machine in the foreground of all human existence and which, by its inherent - almost irresistible - dynamism, gradually estranges man from all inner connection with nature. This process of growing mechanization, so evident in our modern life, jeopardizes the very structure of human society and, thus, contributes to a gradual dissolution of all moral and spiritual perceptions epitomized in the concept of "divine guidance". It is to warn man of this danger that the Qur’an stresses - symbolically and metonymically - the potential evil (ba’s) of "iron" if it is put to wrong use: in other words, the danger of man’s allowing his technological ingenuity to run wild and thus to overwhelm his spiritual consciousness and, ultimately, to destroy all possibility of individual and social happiness.
43  Lit., "those who succour Him and His Apostle", i.e., those who stand up for the cause of God and His Apostle. The meaning is that only they who put God’s spiritual and material gifts to right use can be described as "true believers".
