Allah didn’t say : Men are not allowed to oppress. Or. Women are not allowed to oppress. He said. Don’t oppress another muslim. As an oppressor can be from both genders. 

There are different types of oppression between the genders. When men are oppressed, they shy away from speaking up or getting help. Most men thinks it’s embarrassing to be known as the weak. Especially if the oppressor is a woman. Because of the crying, people often think that women is not at fault. Overlooking the fact that many women are good at manipulation. Getting their way from sobbing and crying. Instead of understanding the situation, most people automatically judge the man as the oppressor. Often times oppression can be so hidden, that only few understand it’s reality. 

Oppression is not allowed in Islam. The supplication of the oppressed is always accepted by Allah. Hazoor Paak ‎ﷺ has said, protect muslims from being an oppressor, and protect muslims when they are oppressed.
