Injustice is deviation from justice and violation of the truth.

　　There are three broad types of injustice:

　　1- {Indeed, the curse of Allah is upon the unjust.} [Quran 11:18]

　　2- {The cause is only against the ones who wrong the people and tyrannize upon the earth without right. Those will have a painful punishment.} [Quran 42:42]

　　3- {He [Moosa] said, “My Lord, indeed I have wronged myself, so forgive me,” and He forgave him. Indeed, He is the Forgiving, the Merciful.} [Quran 28:16]

　　In fact, all three types are considered as doing injustice to oneself as one wrongs oneself when one intends to do injustice.

　　Ath-Thahabi maintained that injustice is a major sin and said that doing injustice to others may take the form of trespassing on their property, abusing them physically or verbally, and attacking the weak. He mentioned the Quranic verses and Prophetic Hadeeths that threaten the unjust. Then he reported that some of the righteous predecessors said, “Do not wrong the weak so as not to be one of the evil strong people.” In addition to this, he mentioned some forms of injustice that he considered to be major sins:

　　- Denying a wife her rights such as dowry, clothing and provision.

　　- {And those cities - We destroyed them when they wronged, and We made for their destruction an appointed time.} [Quran 18:59]

　　· {And your Lord does injustice to no one.}[Quran 18:49]

　　· It was narrated on the authority of Abu Moosa Al-Ash‘ari that the Prophet, , said: “Indeed, Allah gives respite to the oppressor, but when He seizes him, He does not let him escape.”' Then he recited:{And thus is the taking away of your Lord when He takes away the towns [while] they are unjust; surely His taking away is painful [and] strict.}[Quran 11:102] [Al-Bukhari and Muslim]

　　- It was narrated on the authority of Huthayfah that the Prophet, , said: “Do not be blind followers and say: ‘If people do good, we do good, and if people do injustice, we do injustice.’ Adjust yourselves; when people do good, do good, and when they wrong, do not do injustice.”[At-Tirmithi]

　　- ‘Ali ibn Abi Talib said, “The day when the wronged will triumph over the wrongdoer will be far severer than the day when the wrongdoer wronged him.” Mu‘awiyah would say, “I would be terrified to wrong a person who has none but Allah The Exalted to seek His help against me.”

　　- Ibn Mas‘ood said, “When the punishment was removed from the people of Yoonus they all returned the rights of others to the extent that a man would pluck a stone out of the foundation of his house and return it to its owner.”

　　- A sage said, “When you want to do injustice, remember the justice of Allah The Almighty that will be executed against you. When you want to use your strength to wrong others, remember that Allah The Exalted has the strength to punish you. Never, be impressed by someone who sheds blood, as his Assassin never dies.”

　　- While Sulayman ibn ‘Abdul-Malik was on the pulpit, a man said to him, “Remember the Day of Announcement!” Sulayman descended from the pulpit and asked the man, “And what is the Day of Announcement?” The man answered, “Allah The Almighty Says (what means): {Then an announcer will announce between them, “The curse of Allah be on the unjust.”}[Quran 7:44]”

　　- Unforgivable injustice: This type refers to Shirk, from which we seek refuge with Allah The Exalted. Allah The Almighty Says (what means): {Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills.}[Quran 4:48]

　　o A man passed by a person whom Al-Hajjaj had crucified, and said, “O Allah, your leniency with the oppressors has harmed the oppressed.” When the man slept that night he saw in a vision that he entered Paradise, and saw the man who had been crucified in the highest ranks of Paradise; then he heard a caller say, “My leniency with the oppressors has admitted the oppressed people to the highest ranks in Paradise.”

　　- ‘Umar said, “Beware of the supplication of an oppressed man, as it is answered.”

　　- Ibn Taymiyyah said, “People unanimously agree that the consequences of injustice are dire and that the outcomes of justice are good.” He also said that, “Allah The Exalted grants victory to a just state even if it is a non-Islamic state, and lets an unjust state be defeated, even if it is an Islamic state.”
