Quran 33:70 — The Parties (Al-Ahzab)

O you who believe, reverence GOD and utter only the correct utterances.

[33:69] O you who believe, do not be like those who hurt Moses, then GOD absolved him of what they said. He was, in the sight of GOD, honorable.

[33:71] He will then fix your works, and forgive your sins. Those who obey GOD and His messenger have triumphed a great triumph.
