﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن جَآءَكُمْ فَاسِقٌۢ بِنَبَإٍۢ فَتَبَيَّنُوٓا۟ أَن تُصِيبُوا۟ قَوْمًۢا بِجَهَٰلَةٍۢ فَتُصْبِحُوا۟ عَلَىٰ مَا فَعَلْتُمْ نَٰدِمِينَ ﴾

“O YOU who have attained to faith! If any iniquitous person comes to you with a [slanderous] tale, use your discernment, lest you hurt people unwittingly and afterwards be filled with remorse for what you have done.”
