Quran 33:57 — The Parties (Al-Ahzab)

Surely, those who oppose GOD and His messenger, GOD afflicts them with a curse in this life, and in the Hereafter; He has prepared for them a shameful retribution.

[33:56] GOD and His angels help and support the prophet. O you who believe, you shall help and support him, and regard him as he should be regarded.

[33:58] Those who persecute the believing men and the believing women, who did not do anything wrong, have committed not only a falsehood, but also a gross sin.
