On the authority of Abu Dharr al-Ghifari the Prophet (SAW) relates from Allah (SWT): “O My servants, I have forbidden oppression for Myself and have made it forbidden amongst you, so do not oppress one another.”
Allah has commanded us to not only be good to one another but to also stand-up against injustice clearly in Suratul Nisa ayah 135.
“Oh you who believe! Stand out firmly for justice, as witnesses to Allah, even though it be against yourselves, or your parents, or your kin, be he rich or poor, Allah is a better protector to both (than you). So follow not your lusts, lest you may avoid justice, and if you distort your witnesses or refuse to give it, verily, Allah is ever well acquainted with what you do.”
We ask Allah to make us amongst those who always stand firmly on the truth, for justice, and help the oppressed. Ameen
