447. Commandment – O ye who believe! raise not your voices above the voice of the Prophet, and speak not aloud to him, as you speak aloud to one another

[49:3] O ye who believe! raise not your voices above the voice of the Prophet, and speak not aloud to him, as you speak aloud to one another, lest your works become vain while you perceive not. [49:4] Verily those who lower their voices in the presence of the Messenger of Allah are the ones whose hearts Allah has purified for righteousness. For them is forgiveness and a great reward.

[50:29] God will say, ‘Quarrel not in My presence, I gave you the warning beforehand.
