يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِنْ جَاۤءَكُمْ فَاسِقٌۢ بِنَبَاٍ فَتَبَيَّنُوْٓا اَنْ تُصِيْبُوْا قَوْمًاۢ بِجَهَالَةٍ فَتُصْبِحُوْا عَلٰى مَا فَعَلْتُمْ نٰدِمِيْنَ ( الحجرات: ٦ )
Yaaa ayyuhal lazeena aamanoo in jaaa'akum faasqum binaba in fatabaiyanooo an tuseeboo qawmam bijahalatin fatusbihoo 'alaa maa fa'altum naadimeen (al-Ḥujurāt 49:6)
Sahih International:
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. (Al-Hujurat [49] : 6)
1 Mufti Taqi Usmani
O you who believe, if a sinful person brings you a report, verify its correctness, lest you should harm a people out of ignorance, and then become remorseful on what you did.
