The Quran enjoins justice and the middle course in many of its passages. It says: Lo, God commands you that you restore deposits to their owners, and, if you judge
between mankind, that you judge justly (Q. ٤:٥٨). Deal justly; that is nearer to your duty (Q. ٥:٨). And if you give your word, do justice thereto even though it be [against] a kinsman (Q. ٦:١٥٢). Lo, God enjoins justice and kindness, and giving to kinsfolk, and forbids lewdness and abomination and wickedness. He exhorts you in order that you may take heed (Q. ١٦:٩٠).

Certainly, the Quran enjoined justice, and its teachings are in accordance with moral integrity. Accordingly, it admonishes in many places against miserliness, ap‌ prising people of its evil consequences:
And let not those who hoard up that which God has bestowed upon them of His bounty think that it is better for them. No, it is worse for them. That which they hoard will be their collar on the Day of Resurrection. To God belongs the heritage of the heavens and the earth. God is informed of what you do (Q. ٣:١٨٠).

At the same time, the Quran admonishes against extravagance and squandering and points to their evils:
And be not prodigal. Lo, God loves not the prodigals (Q. ٦:١٤١ ). Lo, the squanderers were ever brothers of the devils. And keep not your hand chained to your neck, nor outspread it widespread altogether, lest you sit down rebuked, denuded (Q. ١٧:٢٨-٢٩).

The Quran enjoins perseverance under adversity and forbearance in times of mis‌
fortune. It praises the patient and promises them a great reward:

Verily the steadfast will be paid their wages without stint (Q. ٣٩:١٠). And God loves the steadfast (Q. ٣:١٤٦).

In addition to this, the Quran does not shackle the oppressed person. Rather, it permits him to retaliate against his oppressor in equal measure. This is in order to put an end to corruption and uphold the rule of justice:

And one who attacks you, attack him in the like manner as he attacked you (Q. ٢:١٩٤).

It also permits the heir of the willfully slain to punish the killer:

Whoever is slain wrongfully, We have given power to his heir, but let him not commit excess in slaying (Q. ١٧:٣٣).

By seeking moderation and prescribing rectitude, the Quran combines a good system for the life of this world and for the next, and provides what puts the former to right and ensures happiness in the latter. For, it is the Great Law; the Prophet brought it [so] that, with it, mankind would attain happiness [in this world and the next]. Its laws are not entirely worldly, with no regard to the hereafter, as is the case with the current version of the Torah. The latter, despite its large size, is devoid of any refer‌ ence to the Day of Resurrection; nor does it inform [its followers] about the next world, where good and evil deeds will be recompensed. On the contrary, the Torah says clearly that obedience to God results in wealth in this world and power over people through their subjugation, while disobedience and falling in the eyes of the Lord lead to death and loss of wealth and power.
