49:6

Al-Hujuraat 49:6

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

Yaaa ayyuhal lazeena aamanoo in jaaa'akum faasqum binaba in fatabaiyanooo an tuseeboo qawmam bijahalatin fatusbihoo 'alaa maa fa'altum naadimeen

Believers, when an ungodly person brings to you a piece of news, carefully ascertain its truth, lest you should hurt a people unwittingly and thereafter repent at what you did.
