Allah Does Not Like Publicising Evil

Be careful, Allah does not like publicising evil except by the one who has been wronged

لَّا يُحِبُّ ٱللَّهُ ٱلْجَهْرَ بِٱلسُّوٓءِ مِنَ ٱلْقَوْلِ إِلَّ

ا مَن ظُلِمَ ۚ وَكَانَ ٱللَّهُ سَمِيعًا عَلِيمًا ‎﴿١٤٨﴾‏ إِن تُبْدُوا۟ خَيْرًا أَوْ تُخْفُوهُ أَوْ تَعْفُوا۟ عَن سُوٓءٍ فَإِنَّ ٱللَّهَ كَانَ عَفُوًّا قَدِيرًا ‎﴿١٤٩

‏

Allah does not like the public mention of evil except by one who has been wronged. And ever is Allah Hearing and Knowing. (148) If [instead] you show [some] good or conceal it or pardon an offense - indeed, Allah is ever Pardoning and Competent. (149) 

(Quran, An Nisa 4:148-149)
