To what extent is it permissible to use the phrase "I'm going to make you feel as if God never created you," which is said for threatening or intimidating purposes?

The phrase "I will make Allah uncreate you" implies a threat to do whatever one wishes to an opponent, considering them as nothing. A Muslim must avoid this phrase because its literal meaning is incorrect; something that exists cannot be considered non-existent. A Muslim is commanded to guard their tongue and avoid words that might be misunderstood, especially those related to Allah. Disputes between Muslims should not escalate to threats of killing or intimidation, as this is among the gravest sins. This phrase contains arrogance, tyranny, and blameworthy boasting. Allah Almighty says: ﴿ And do not turn your cheek in scorn toward people or walk through the earth exultantly. Indeed, Allah does not like every self-deluded and boastful person ﴾. Muslims are commanded to brotherhood and gentleness. Allah Almighty says: ﴿ Muhammad is the Messenger of Allah; and those with him are strong against disbelievers, merciful among themselves ﴾, and to repel opponents with gentleness. Allah Almighty says: ﴿ Repel [evil] with that which is better; then, suddenly, the one whom between you and him was enmity will become as though he was a devoted friend ﴾.
