Quran 49:6 Al-Hujurat, ayah 6 of 18

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن جَآءَكُمْ فَاسِقٌۢ بِنَبَإٍ فَتَبَيَّنُوٓا۟ أَن تُصِيبُوا۟ قَوْمًۢا بِجَهَـٰلَةٍ فَتُصْبِحُوا۟ عَلَىٰ مَا فَعَلْتُمْ نَـٰدِمِينَ ۝٦

49:6 O ye who believe! If an evil-liver bring you tidings, verify it, lest ye smite some folk in ignorance and afterward repent of what ye did.
