Al Hujurat Ayah 6

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِن جَآءَكُمْ فَاسِقُۢ بِنَبَإٍ فَتَبَيَّنُوٓاْ أَن تُصِيبُواْ قَوْمَۢا بِجَهَـٰلَةٍ فَتُصْبِحُواْ عَلَىٰ مَا فَعَلْتُمْ نَـٰدِمِينَ ٦ O believers, if an evildoer brings you any news, verify ?it? so you do not harm people unknowingly, becoming regretful for what you have done.
