AL HUJURAAT — Ayat 6

يَا أَيُّهَا الَّذِينَ آمَنُوا إِن جَاءكُمْ فَاسِقٌ بِنَبَأٍ فَتَبَيَّنُوا أَن تُصِيبُوا قَوْمًا بِجَهَالَةٍ فَتُصْبِحُوا عَلَى مَا فَعَلْتُمْ نَادِمِينَ

O you who have believed, if there comes to you a disobedient one with information, investigate, lest you harm a people out of ignorance and become, over what you have done, regretful.
