﴿ ۞ لَّا يُحِبُّ ٱللَّهُ ٱلْجَهْرَ بِٱلسُّوٓءِ مِنَ ٱلْقَوْلِ إِلَّا مَن ظُلِمَ ۚ وَكَانَ ٱللَّهُ سَمِيعًا عَلِيمًا ﴾

“God does not like any evil to be mentioned openly, unless it be by him who has been wronged (thereby) And God is indeed all-hearing, all-knowing,”

God does not like the utterance of evil words out loud by any person that is to say He will punish him for it unless a person has been wronged in which case He would not punish him for uttering it out loud when he is informing others of the wrong done to him by the wrong-doer or summoning them against him. God is ever Hearer of what is said Knower of what is done.
