Surah An-Nisa — Ayah 148 (4:148)
۞ لَّا يُحِبُّ ٱللَّهُ ٱلۡجَهۡرَ بِٱلسُّوٓءِ مِنَ ٱلۡقَوۡلِ إِلَّا مَن ظُلِمَۚ وَكَانَ ٱللَّهُ سَمِيعًا عَلِيمًا ١٤٨
English translation (Saheeh International)
Allāh does not like the public mention of evil except by one who has been wronged. And ever is Allāh Hearing and Knowing.
Brief commentary
Allah does not like evil statements to be made public. He dislikes that and warns against it. However, if a person is wronged, he may mention the evil in order to complain against the guilty party, to call against him and to retaliate with similar words. In this case, too, it is better for the one who was wronged to be patient and not to disclose the matter. Allah hears your statements and knows your intentions, so be careful of saying or intending anything evil.
