A--- First: the Major Injustice:

Allah the Almighty says: {And invoke not besides Allah any such that will neither profit you nor hurt you, but if (in case) you did so, you shall certainly be one of the Zalimun (polytheists and wrong-doers)}. (Yunus, 106)

Allah the Almighty says: {Verily, joining others in worship with Allah is a great Zulm (injustice) indeed}. (Luqman, 13)

Allah the Almighty says: {Verily, whosoever sets up partners (in worship) with Allah, then Allah has forbidden Paradise to him, and the Fire will be his abode. And for the Zalimun (polytheists and wrong-doers) there are no helpers}. (Al-Ma'idah, 72)

Second: the Minor Injustice:

Allah the Almighty says: {And fear Allah your Lord (O Muslims), And turn them not out of their (husband's) homes nor shall they (themselves) leave, except in case they are guilty of some open illegal sexual intercourse. And those are the set limits of Allah.

And whosoever transgresses the set limits of Allah, then indeed he has been unjust to himself}. (At- Talaq, 1)

Allah the Almighty says: {But do not take them back to hurt them, and whoever does that, then he has wronged himself}. (AlBaqarah, 231)
