يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِن جَآءَكُمۡ فَاسِقُۢ بِنَبَإٖ فَتَبَيَّنُوٓاْ أَن تُصِيبُواْ قَوۡمَۢا بِجَهَٰلَةٖ فَتُصۡبِحُواْ عَلَىٰ مَا فَعَلۡتُمۡ نَٰدِمِينَ

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

O ye who believe! If a wicked person comes to you with any news, ascertain the truth, lest ye harm people unwittingly, and afterwards become full of repentance for what ye have done.

— Al-Hujurat (ٱلحُجُرَات), 49:6
