Quran 49:1 — The Walls (Al-Hujurat)

O you who believe, do not place your opinion above that of GOD and His messenger. You shall reverence GOD. GOD is Hearer, Omniscient.

[49:0] In the name of God, Most Gracious, Most Merciful.

[49:2] O you who believe, do not raise your voices above the voice of the prophet,* nor shall you shout at him as you shout at each other, lest your works become nullified while you do not perceive.
